Struct Oid 

pub struct Oid(/* private fields */);

A SHA-256 object identifier.

Stored as the raw 32 bytes; rendered as 64 lowercase hex characters by fmt::Display. Construction via Oid::from_hex enforces the spec’s strict-lowercase, exactly-64-hex-character format.

Implementations

impl Oid

pub const EMPTY: Oid

SHA-256 of the empty input. The OID of the empty pointer.

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Construct an OID from raw 32 hash bytes (e.g. the output of a streaming SHA-256 hasher).

pub fn from_hex(s: &str) -> Result<Self, OidParseError>

Parse an OID from its 64-character lowercase hex form.

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

Borrow the raw 32-byte hash.

Trait Implementations

impl Clone for Oid

fn clone(&self) -> Oid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Oid

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

Formats the value using the given formatter.

impl Display for Oid

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

Formats the value using the given formatter.

impl FromStr for Oid

type Err = OidParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Oid

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 Ord for Oid

fn cmp(&self, other: &Oid) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Oid

fn eq(&self, other: &Oid) -> 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.

impl PartialOrd for Oid

fn partial_cmp(&self, other: &Oid) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
