Struct SegmentHash 

pub struct SegmentHash { /* private fields */ }

Hash value representing a media segment.

Implementations

impl SegmentHash

pub fn new(data: [u8; 32], frame_count: usize) -> Self

Create a new segment hash from raw bytes and frame count.

pub fn from_bytes(bytes: &[u8], frame_count: usize) -> Self

Construct a segment hash by XOR-folding a byte slice into 32 bytes.

pub fn is_match(&self, other: &Self, max_diff_bits: u32) -> bool

Returns true if this hash matches another within a given Hamming-bit tolerance.

pub fn as_bytes(&self) -> &[u8; 32]

Returns the raw bytes of this hash.

pub fn frame_count(&self) -> usize

Returns the number of frames this hash covers.

Trait Implementations

impl Clone for SegmentHash

fn clone(&self) -> SegmentHash

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SegmentHash

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

Formats the value using the given formatter.

impl Eq for SegmentHash

impl Hash for SegmentHash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SegmentHash

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
