Struct Namespace 

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

Dot-separated namespace.

Implementations

impl Namespace

pub const fn new() -> Self

Creates an empty namespace.

pub fn check(&self) -> bool

Returns true when all namespace tokens are non-empty, trimmed and short enough.

pub fn add(&mut self, name: &str)

Appends a non-empty token to the namespace.

pub fn root(&self) -> Self

Returns the top-level namespace segment.

pub fn parent(&self) -> Self

Returns the direct parent namespace.

pub fn key(&self) -> String

Returns the last namespace segment.

pub const fn level(&self) -> usize

Returns the number of namespace segments.

pub fn at_level(&self, level: usize) -> Self

Returns the namespace truncated to level segments.

pub const fn is_empty(&self) -> bool

Returns true when the namespace has no segments.

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

Returns true when self is a strict ancestor of other.

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

Returns true when self is an ancestor of other or both are equal.

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

Returns true when self is a strict descendant of other.

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

Returns true when self is the direct parent of other.

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

Returns true when self is the direct child of other.

pub const fn is_top_level(&self) -> bool

Returns true when the namespace has a single segment.

Trait Implementations

impl BorshDeserialize for Namespace

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Namespace

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for Namespace

fn clone(&self) -> Namespace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Namespace

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

Formats the value using the given formatter.

impl Default for Namespace

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Namespace

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Namespace

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

Formats the value using the given formatter.

impl From<&str> for Namespace

fn from(str: &str) -> Self

Converts to this type from the input type.

impl From<String> for Namespace

fn from(str: String) -> Self

Converts to this type from the input type.

impl Hash for Namespace

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 Namespace

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

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

fn partial_cmp(&self, other: &Namespace) -> 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 Namespace

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Namespace
