Trait BincodeRead

pub trait BincodeRead<'storage>: Read {
    // Required methods
    fn forward_read_str<V>(
        &mut self,
        length: usize,
        visitor: V,
    ) -> Result<V::Value>
       where V: Visitor<'storage>;
    fn get_byte_buffer(&mut self, length: usize) -> Result<Vec<u8>>;
    fn forward_read_bytes<V>(
        &mut self,
        length: usize,
        visitor: V,
    ) -> Result<V::Value>
       where V: Visitor<'storage>;
}

An optional Read trait for advanced Bincode usage.

It is highly recommended to use bincode with io::Read or &[u8] before implementing a custom BincodeRead.

The forward_read_* methods are necessary because some byte sources want to pass a long-lived borrow to the visitor and others want to pass a transient slice.

Required Methods

fn forward_read_str<V>(&mut self, length: usize, visitor: V) -> Result<V::Value>

where V: Visitor<'storage>,

Check that the next length bytes are a valid string and pass it on to the serde reader.

fn get_byte_buffer(&mut self, length: usize) -> Result<Vec<u8>>

Transfer ownership of the next length bytes to the caller.

fn forward_read_bytes<V>( &mut self, length: usize, visitor: V, ) -> Result<V::Value>

where V: Visitor<'storage>,

Pass a slice of the next length bytes on to the serde reader.

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.
