Method wasm_binary_file

crates/wasmtime/src/compile/code_builder.rs:169–173

Reads the `file` specified for the WebAssembly bytes that are going to be compiled. This method will read `file` from the filesystem and interpret it as a WebAssembly binary. A DWARF package file will be probed using the root of `file` and with a `.dwp` extension. If found, it will be loaded and DWARF fusion performed. # Errors This method will return an error if WebAssembly bytes have already

(&mut self, file: &'a Path)

    /// If DWARF fusion is performed and the DWARF packaged file cannot be read
    /// then an error will be returned.
    pub fn wasm_binary_file(&mut self, file: &'a Path) -> Result<&mut Self> {
        let wasm = std::fs::read(file)
            .with_context(|| format!("failed to read input file: {}", file.display()))?;
        self.wasm_binary(wasm, Some(file))
    }

    /// Equivalent of [`CodeBuilder::wasm_binary_file`] that also accepts the
    /// WebAssembly text format.
