WasmFile

Struct WasmFile 

Source
pub struct WasmFile {
    pub bytes: Vec<u8>,
    pub version: u32,
    pub sections: Vec<Section>,
}
Expand description

A parsed WASM module. bytes is the verbatim input; the sections list records where each section starts and ends so callers can read or rewrite them without re-parsing.

Fields§

§bytes: Vec<u8>§version: u32§sections: Vec<Section>

Implementations§

Source§

impl WasmFile

Source

pub fn parse(bytes: &[u8]) -> Result<Self>

Parse bytes into a WasmFile. The bytes are retained verbatim so Self::write_to_vec can reproduce them.

Source

pub fn write_to_vec(&self) -> Vec<u8>

Reproduce the original bytes. Currently a clone — when section editing lands the layout-rebuild logic will live here.

Source

pub fn section_body(&self, section: &Section) -> &[u8]

Body bytes of section (excluding the id + size header).

Source

pub fn custom_section_name(&self, section: &Section) -> Option<String>

For a custom (id = 0) section, return its decoded name (UTF-8). The name is a LEB128-length-prefixed string at the start of the body. Returns None for non-custom sections or malformed names.
