Trait DecodeTarget

pub trait DecodeTarget {
    // Required method
    fn decode_with(
        &mut self,
        max_len: usize,
        f: impl for<'a> FnOnce(&'a mut [u8]) -> Result<usize>,
    ) -> Result<usize>;
}

Represents a buffer that can be decoded into. See DecodeBuilder::onto and the provided implementations for more details.

Required Methods

fn decode_with( &mut self, max_len: usize, f: impl for<'a> FnOnce(&'a mut [u8]) -> Result<usize>, ) -> Result<usize>

Decodes into this buffer, provides the maximum length for implementations that wish to preallocate space, along with a function that will write bytes into the buffer and return the length written to it.

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.
