Implementations

impl Permission

pub const fn satisfies(self, required: Permission) -> bool

判断当前权限是否满足目标权限。

Trait Implementations

impl Clone for Permission

fn clone(&self) -> Permission

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Permission

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

Formats the value using the given formatter.

impl Default for Permission

fn default() -> Permission

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Permission

fn deserialize<D>( deserializer: D, ) -> Result<Permission, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Permission

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

Formats the value using the given formatter.

impl<'_derivative_strum> From<&'_derivative_strum Permission> for &'static str

fn from(x: &'_derivative_strum Permission) -> &'static str

Converts to this type from the input type.

impl From<Permission> for &'static str

fn from(x: Permission) -> &'static str

Converts to this type from the input type.

impl FromStr for Permission

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Permission, <Permission as FromStr>::Err>

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

impl PartialEq for Permission

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

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

impl Serialize for Permission

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for Permission

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Permission, <Permission as TryFrom<&str>>::Error>

Performs the conversion.

impl Copy for Permission

impl StructuralPartialEq for Permission
