A trait to help to write data to a writer at a specific offset.

Required Methods

fn write_at(&mut self, offset: u64, buf: &[u8]) -> Result<usize>

Writes data to the writer at a specific offset. Returns the number of bytes written.

fn write_all_at(&mut self, offset: u64, buf: &[u8]) -> Result<()>

Writes all data to the writer at a specific offset. Returns an error if the write fails.

fn write_struct_at<V: StructPack>( &mut self, offset: u64, value: &V, big: bool, encoding: Encoding, info: &Option<Box<dyn Any>>, ) -> Result<()>

Write a struct at a specific offset.

Provided Methods

Writes a u8 at a specific offset.

fn write_u16_at(&mut self, offset: u64, value: u16) -> Result<()>

Writes a u16 at a specific offset in little-endian order.

fn write_u16_be_at(&mut self, offset: u64, value: u16) -> Result<()>

fn write_cstring_at(&mut self, offset: u64, value: &CString) -> Result<()>

Writes a C-style string (null-terminated) at a specific offset.

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.
