Struct short_hex_str::ShortHexStr

pub struct ShortHexStr(_);

An efficient container for formatting a byte slice as a hex-formatted string, stored on the stack.

Using ShortHexStr instead of hex::encode is about 3-4x faster on a recent MBP 2019 (~48 ns/iter vs ~170 ns/iter) in an artifical micro benchmark.

Implementations

impl ShortHexStr

pub const SOURCE_LENGTH: usize = 4usize

pub const LENGTH: usize = 8usize

pub fn try_from_bytes( src_bytes: &[u8] ) -> Result<ShortHexStr, InputTooShortError>

Format a new ShortHexStr from a byte slice.

Returns Err(InputTooShortError) if the input byte slice length is less than SOURCE_LENGTH bytes.

pub fn as_str(&self) -> &str

Trait Implementations

impl Clone for ShortHexStr

fn clone(&self) -> ShortHexStr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShortHexStr

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

Formats the value using the given formatter.

impl Display for ShortHexStr

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

Formats the value using the given formatter.

impl Hash for ShortHexStr

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 ShortHexStr

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ShortHexStr> for ShortHexStr

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<ShortHexStr> for ShortHexStr

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for ShortHexStr

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.
