Functions and values

Function or value	Description
`Map.chooseValues mapping source` Full Usage: `Map.chooseValues mapping source` Parameters: mapping : `'T -> 'a option` - The mapping function. source : `Map<'Key, 'T>` - The input Map. Returns: `Map<'Key, 'a>` Returns Map with values x for each Map value where the function returns Some(x).	Applies given function to each value of the given Map. mapping : `'T -> 'a option` The mapping function. source : `Map<'Key, 'T>` The input Map. Returns: `Map<'Key, 'a>` Returns Map with values x for each Map value where the function returns Some(x).
`Map.choosei f x` Full Usage: `Map.choosei f x` Parameters: f : `'Key -> 'T -> 'U option` - The mapping function, taking key and element as parameters. x : `Map<'Key, 'T>` - The input map. Returns: `Map<'Key, 'U>` Returns Map with values (k, v) for each Map value where the function returns Some(v).	Same as chooseValues but with access to the key. f : `'Key -> 'T -> 'U option` The mapping function, taking key and element as parameters. x : `Map<'Key, 'T>` The input map. Returns: `Map<'Key, 'U>` Returns Map with values (k, v) for each Map value where the function returns Some(v).
`Map.intersect source1 source2` Full Usage: `Map.intersect source1 source2` Parameters: source1 : `Map<'Key, 'T>` source2 : `Map<'Key, 'T>` Returns: `Map<'Key, 'T>`	Returns the intersection of two maps, preferring values from the first in case of duplicate keys. source1 : `Map<'Key, 'T>` source2 : `Map<'Key, 'T>` Returns: `Map<'Key, 'T>`
`Map.intersectWith combiner source1 source2` Full Usage: `Map.intersectWith combiner source1 source2` Parameters: combiner : `'T -> 'T -> 'T` source1 : `Map<'Key, 'T>` source2 : `Map<'Key, 'T>` Returns: `Map<'Key, 'T>`	Returns the intersection of two maps, using the combiner function for duplicate keys. combiner : `'T -> 'T -> 'T` source1 : `Map<'Key, 'T>` source2 : `Map<'Key, 'T>` Returns: `Map<'Key, 'T>`
`Map.keys source` Full Usage: `Map.keys source` Parameters: source : `Map<'Key, 'T>` - The input map. Returns: `'Key seq` A seq of the keys in the map.	Returns the keys of the given map. Note: this function has since been added to FSharp.Core. It will be removed in next major release of FSharpPlus. source : `Map<'Key, 'T>` The input map. Returns: `'Key seq` A seq of the keys in the map.
`Map.mapValues f x` Full Usage: `Map.mapValues f x` Parameters: f : `'T -> 'h` - The mapping function - takes only the value, and returns the mapped value. x : `Map<'Key, 'T>` - The input Map. Returns: `Map<'Key, 'h>` The mapped Map.	Maps the values of the original Map. The core `Map.map` function maps over values too, but it passes both key and value to the mapping function. f : `'T -> 'h` The mapping function - takes only the value, and returns the mapped value. x : `Map<'Key, 'T>` The input Map. Returns: `Map<'Key, 'h>` The mapped Map.
`Map.mapValues2 f x y` Full Usage: `Map.mapValues2 f x y` Parameters: f : `'T1 -> 'T2 -> 'b` - The mapping function. x : `Map<'Key, 'T1>` - The first input Map. y : `Map<'Key, 'T2>` - The second input Map. Returns: `Map<'Key, 'b>` The mapped Map.	Maps values of two Maps. Keys that are not present on both Maps are dropped. f : `'T1 -> 'T2 -> 'b` The mapping function. x : `Map<'Key, 'T1>` The first input Map. y : `Map<'Key, 'T2>` The second input Map. Returns: `Map<'Key, 'b>` The mapped Map.
`Map.mapValues3 mapping x y z` Full Usage: `Map.mapValues3 mapping x y z` Parameters: mapping : `'T1 -> 'T2 -> 'T3 -> 'b` - The mapping function. x : `Map<'Key, 'T1>` - First input Map. y : `Map<'Key, 'T2>` - Second input Map. z : `Map<'Key, 'T3>` - Third input Map. Returns: `Map<'Key, 'b>` The mapped Map.	Combines values from three maps using mapping function. Keys that are not present on every Map are dropped. mapping : `'T1 -> 'T2 -> 'T3 -> 'b` The mapping function. x : `Map<'Key, 'T1>` First input Map. y : `Map<'Key, 'T2>` Second input Map. z : `Map<'Key, 'T3>` Third input Map. Returns: `Map<'Key, 'b>` The mapped Map.
`Map.union source altSource` Full Usage: `Map.union source altSource` Parameters: source : `Map<'Key, 'T>` altSource : `Map<'Key, 'T>` Returns: `Map<'Key, 'T>`	Returns the union of two maps, preferring values from the first in case of duplicate keys. source : `Map<'Key, 'T>` altSource : `Map<'Key, 'T>` Returns: `Map<'Key, 'T>`
