Struct TypedDict

pub struct TypedDict<'a, T> { /* private fields */ }

Writer for a dictionary mapping to a fixed type.

Implementations

impl<'a, T> TypedDict<'a, T>

pub fn wrap(dict: Dict<'a>) -> Self

Wrap a dictionary to make it type-safe.

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn pair(&mut self, key: Name<'_>, value: T) -> &mut Self

where T: Primitive,

Write a key-value pair.

pub fn pairs<'n>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

where T: Primitive,

Write a sequence of key-value pairs.

pub fn insert<'b>(&'b mut self, key: Name<'_>) -> <T as Rewrite<'_>>::Output

where T: Writer<'a> + Rewrite<'b>,

Start writing a pair with the typed writer.

Returns T but with its lifetime rewritten from 'a to 'b.
