Trait EncodableLen

Source 
pub trait EncodableLen: Encodable<CodecLen> {
    // Provided method
    fn encoded_size(&self) -> IoResult<usize> { ... }
}
Expand description

A type that can compute the size of its encoded form without actual encoding.

This trait is automatically implemented for all types that implement Encodable with CodecLen.

See CodecLen for details on length-based encoding.

§Vendored

This is adapted work from encode.

Provided Methods§

Source

fn encoded_size(&self) -> IoResult<usize>

Computes the size of self when encoded.

This method simulates encoding without writing any data, allowing for preallocation or buffer sizing.
