Expand description

An all-safe-code endian-aware integer parsing trait.

These methods use safe code to get a subslice from the the byte slice $data at the given $off as a [u8; size_of<$typ>], then calls the corresponding safe endian-aware conversion on it.

These use checked integer math and returns a ParseError on overflow or if $data did not contain enough bytes at $off to perform the conversion.

Required Methods§

Source

fn from_ei_data(ei_data: u8) -> Result<Self, ParseError>

Get an endian-aware integer parsing spec for an ELF FileHeader’s ident[EI_DATA] byte.

Returns an UnsupportedElfEndianness if this spec doesn’t support parsing the byte-order represented by ei_data. If you’re seeing this error, are you trying to read files of any endianness? i.e. did you want to use AnyEndian?

fn is_little(self) -> bool

Provided Methods§

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.
