Struct mozjpeg_sys::jpeg_common_struct[−][src]

#[repr(C)]pub struct jpeg_common_struct {
    pub err: *mut jpeg_error_mgr,
    pub mem: *mut jpeg_memory_mgr,
    pub progress: *mut jpeg_progress_mgr,
    pub client_data: *mut c_void,
    pub is_decompressor: boolean,
    pub global_state: c_int,
}

Routines that are to be used by both halves of the library are declared to receive a pointer to this structure. There are no actual instances of jpeg_common_struct, only of jpeg_compress_struct and jpeg_decompress_struct.

Fields

err: *mut jpeg_error_mgrmem: *mut jpeg_memory_mgrprogress: *mut jpeg_progress_mgr

Progress monitor, or NULL if none

client_data: *mut c_void

Available for use by application

is_decompressor: boolean

So common code can tell which is which

global_state: c_int

For checking call sequence validity
