}

A trait for offsets with a DWARF section.

This allows consumers to choose a size that is appropriate for their address space.

Required Methods

fn from_u8(offset: u8) -> Self

Convert a u8 to an offset.

fn from_u16(offset: u16) -> Self

Convert a u16 to an offset.

fn from_i16(offset: i16) -> Self

Convert an i16 to an offset.

fn from_u32(offset: u32) -> Self

Convert a u32 to an offset.

fn from_u64(offset: u64) -> Result<Self>

Convert a u64 to an offset.

Returns Error::UnsupportedOffset if the value is too large.

fn into_u64(self) -> u64

Convert an offset to a u64.

fn wrapping_add(self, other: Self) -> Self

Wrapping (modular) addition. Computes self + other.

fn checked_sub(self, other: Self) -> Option<Self>

Checked subtraction. Computes self - other.

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.
