Struct agilulf_protocol::Slice

pub struct Slice(pub Vec<u8>);

In the most time of this project, the key or value will be represented by a so called Slice (actually not a slice but a Vec<u8>).

It is not a good design (for both egineering and efficiency). But it's a compromise between programming efficiency and runtime efficiency.

Good Part:

It avoids the battle with lifetime. With Future and async/await used in this project, complicated lifetime should be avoided at most time. Or I will fall into the blackhole of lifetime contradiction.

Bad Part:

When facing the low level operation, or the memory is gotten from mmap, using vector may lead to unexpected error. One of them is unexpected free(). While dropping a vector, it will automatically free the memory owned by it. However, if I use from_raw_parts and make up a vector from memmap memory, it will drop this memmaped memory and lead to a panic.

Trait Implementations

impl Default for Slice

fn default() -> Self

Returns the "default value" for a type.

impl PartialEq<Slice> for Slice

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

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for Slice

fn clone(&self) -> Slice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialOrd<Slice> for Slice

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

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

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

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

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

#[must_use] 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 Ord for Slice

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl Eq for Slice

impl Debug for Slice

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

Formats the value using the given formatter.
