The implementation of a memory mapper.

Fields

block_size_hint: usize

A hint to libsqsh to use this block size if the user did not specify one.

init: Option<unsafe extern "C" fn(mapper: *mut SqshMapper, input: *const c_void, size: *mut usize) -> c_int>

The initialization function for the mapper. Use sqsh_mapper_set_user_data() to set custom user data.

map: Option<unsafe extern "C" fn(mapper: *const SqshMapper, offset: sqsh_index_t, size: usize, data: *mut *mut u8) -> c_int>

The function that maps a block of data into memory.

unmap: Option<unsafe extern "C" fn(mapper: *const SqshMapper, data: *mut u8, size: usize) -> c_int>

The function that unmaps a block of data from memory.

cleanup: Option<unsafe extern "C" fn(mapper: *mut SqshMapper) -> c_int>

The cleanup function for the mapper.
