Fields for map types

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

vtable: &'shape MapVTable

vtable for interacting with the map

k: fn() -> &'shape Shape<'shape>

shape of the keys in the map

v: fn() -> &'shape Shape<'shape>

shape of the values in the map

Implementations

impl<'shape> MapDef<'shape>

pub const fn builder() -> MapDefBuilder<'shape>

Returns a builder for MapDef

pub fn k(&self) -> &'shape Shape<'shape>

Returns the shape of the keys of the map

pub fn v(&self) -> &'shape Shape<'shape>

Returns the shape of the values of the map

Trait Implementations

impl<'shape> Clone for MapDef<'shape>

fn clone(&self) -> MapDef<'shape>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'shape> Debug for MapDef<'shape>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'shape> Hash for MapDef<'shape>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'shape> PartialEq for MapDef<'shape>

fn eq(&self, other: &MapDef<'shape>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
