Implementations

impl<R: Read + Seek, W: Write + Seek, A: Fn(u64) -> Result<u64>, O: Fn(u64) -> Result<u64>> BinaryPatcher<R, W, A, O>

pub fn new( input: R, output: W, address_to_offset: A, offset_to_address: O, ) -> Result<Self>

Creates a new BinaryPatcher with the specified input and output streams.

pub fn copy_up_to(&mut self, original_offset: u64) -> Result<()>

Copies data from the input stream to the output stream up to the specified address of original stream.

pub fn map_offset(&mut self, original_offset: u64) -> Result<u64>

Maps an original offset to a new offset in the output stream.

pub fn replace_bytes( &mut self, original_length: u64, new_data: &[u8], ) -> Result<()>

Replaces bytes in the output stream with new data, starting from the current position in the input stream.

• original_length - The length of the original data to be replaced.
• new_data - The new data to write to the output stream.

pub fn replace_bytes_with_write<F: Fn(&mut W) -> Result<()>>( &mut self, original_length: u64, write: F, ) -> Result<()>

Replaces bytes in the output stream with new data, starting from the current position in the input stream.

• original_length - The length of the original data to be replaced.
• write - A function that writes the new data to the output stream.

pub fn patch_u32_address(&mut self, original_offset: u64) -> Result<()>

Patches a u32 address in the output stream at the specified original offset.
