结构体 AVProbeData 

#[repr(C)]
pub struct AVProbeData {
    pub filename: *const c_char,
    pub buf: *mut c_uchar,
    pub buf_size: c_int,
    pub mime_type: *const c_char,
}

This structure contains the data a format has to probe a file.

Fields

filename: *const c_char

buf: *mut c_uchar

< Buffer must have AVPROBE_PADDING_SIZE of extra allocated bytes filled with zero.

buf_size: c_int

< Size of buf except extra allocated bytes

mime_type: *const c_char

< mime_type, when known.

trait 实现

impl Clone for AVProbeData

fn clone(&self) -> AVProbeData

Returns a duplicate of the value. 阅读更多

impl Debug for AVProbeData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

使用给定的格式化器格式化该值。 阅读更多

impl PartialEq for AVProbeData

fn eq(&self, other: &AVProbeData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

测试 !=。默认实现几乎总是足够的，没有充分理由不应被重写。
