Trait HasField 

pub trait HasField<Field, T, R>
where
    Field: TypedString,
{
    // Required methods
    fn get_field<'a>(&'a self) -> &'a T
       where Field: 'a;
    fn get_field_mut<'a>(&'a mut self) -> &'a mut T
       where Field: 'a;
    fn take_field(self) -> T;
}

A trait that indicate that an anonymous struct contains a certain field.

Generic parameters

• Field: Typed field name, see stringz::ident!.
• T: The type of data carried by the field.
• R: Type used to indicate the position of the field in the struct. Usually automatically inferred by Rust.

Example

See the section “as generic type”.

Required Methods

fn get_field<'a>(&'a self) -> &'a T

where Field: 'a,

Get the immutable reference to the data carried by the field.

fn get_field_mut<'a>(&'a mut self) -> &'a mut T

where Field: 'a,

Get the mutable reference to the data carried by the field.

fn take_field(self) -> T

Consume the struct and take the data carried by the field.

Implementations on Foreign Types

impl<Field, T, R, First, Other> HasField<Field, T, R> for Tuple<First, Other>

where Field: TypedString, Self: Search<(Field, T), R>,

fn get_field<'a>(&'a self) -> &'a T

where Field: 'a,

fn get_field_mut<'a>(&'a mut self) -> &'a mut T

where Field: 'a,

fn take_field(self) -> T
