Struct wasmbin::builtins::Blob

pub struct Blob<T: Decode> {
    pub contents: Lazy<T>,
}

A length-prefixed blob that can be skipped over during decoding.

Fields

contents: Lazy<T>

Lazily-decoded contents of the blob.

Methods from Deref<Target = Lazy<T>>

pub fn try_as_raw(&self) -> Result<&UnparsedBytes, &T>

Retrieve the raw bytes if the value has not been modified yet.

pub fn try_contents(&self) -> Result<&T, DecodeError>

Retrieve a reference to the inner value, decoding it if it wasn’t already.

pub fn try_contents_mut(&mut self) -> Result<&mut T, DecodeError>

Retrieve a mutable reference to the inner value, decoding it if it wasn’t already.

This will invalidate the original raw bytes.
