Enum Kind

pub enum Kind {
    Sha1 = 1,
}

Denotes the kind of function to produce a ObjectId.

Variants

Sha1 = 1

The Sha1 hash with 160 bits.

Implementations

impl Kind

pub const fn shortest() -> Self

Returns the shortest hash we support.

pub const fn longest() -> Self

Returns the longest hash we support.

pub const fn hex_buf() -> [u8; 40]

Returns a buffer suitable to hold the longest possible hash in hex.

pub const fn buf() -> [u8; 20]

Returns a buffer suitable to hold the longest possible hash as raw bytes.

pub const fn len_in_hex(&self) -> usize

Returns the amount of bytes needed to encode this instance as hexadecimal characters.

pub const fn len_in_bytes(&self) -> usize

Returns the amount of bytes taken up by the hash of this instance.

pub const fn from_hex_len(hex_len: usize) -> Option<Self>

Returns the kind of hash that would fit the given hex_len, or None if there is no fitting hash. Note that 0 as hex_len up to 40 always yields Sha1.

pub fn null_ref(&self) -> &'static oid

Create a shared null-id of our hash kind.

pub const fn null(&self) -> ObjectId

Create an owned null-id of our hash kind.

Trait Implementations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Kind

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

Formats the value using the given formatter.

impl Default for Kind

fn default() -> Kind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Kind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Kind

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

Formats the value using the given formatter.

impl FromStr for Kind

type Err = String

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 Kind

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 Kind

fn cmp(&self, other: &Kind) -> 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 Kind

fn eq(&self, other: &Kind) -> 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 Kind

fn partial_cmp(&self, other: &Kind) -> 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.

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.

impl Serialize for Kind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u8> for Kind

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
