Expand description

This trait abstracts over decoders that can decode lazy values using LazyState:

Required Methods§

Source

fn set_lazy_state(&mut self, state: LazyState)

Source

fn get_lazy_state(&self) -> LazyState

Provided Methods§

Source

fn read_lazy<T>(&mut self) -> LazyValue<T>

Source

fn read_lazy_array<T>(&mut self, len: usize) -> LazyArray<T>

Source

fn read_lazy_table<I, T>(&mut self, width: usize, len: usize) -> LazyTable<I, T>

Source

fn read_lazy_offset_then<T>(&mut self, f: impl Fn(NonZero<usize>) -> T) -> T

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
