Struct AccountComponentName 

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

The canonical name of an account component.

Names follow the same syntax as StorageSlotName: ::-separated components consisting of ASCII alphanumeric characters or underscores, with at least two components and no leading underscore on any component. See the type-level docs of StorageSlotName for the full grammar.

The name is stored as a Cow<'static, str> so that hard-coded component names (e.g. the NAME constant on each standard component) can be turned into typed names via AccountComponentName::from_static_str without any runtime allocation, while runtime names (parsed strings, etc.) can still be constructed via AccountComponentName::new.

Implementations

impl AccountComponentName

pub const fn from_static_str(name: &'static str) -> Self

Constructs an AccountComponentName from a &'static str at compile time.

Panics

Panics if name does not satisfy the validity rules described in the type-level documentation of AccountComponentName.

pub fn new( name: impl Into<Cow<'static, str>>, ) -> Result<Self, AccountComponentNameError>

Constructs an AccountComponentName from any value convertible into a Cow<'static, str>.

Errors

Returns an error if name is not a valid component name (see the type-level docs).

pub fn as_str(&self) -> &str

Returns the component name as a string slice.

Trait Implementations

impl Clone for AccountComponentName

fn clone(&self) -> AccountComponentName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountComponentName

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

Formats the value using the given formatter.

impl Display for AccountComponentName

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

Formats the value using the given formatter.

impl From<AccountComponentName> for String

fn from(name: AccountComponentName) -> Self

Converts to this type from the input type.

impl FromStr for AccountComponentName

type Err = AccountComponentNameError

The associated error which can be returned from parsing.

fn from_str(string: &str) -> Result<Self, Self::Err>

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

impl Hash for AccountComponentName

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 AccountComponentName

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

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

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

type Error = AccountComponentNameError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<String> for AccountComponentName

type Error = AccountComponentNameError

The type returned in the event of a conversion error.

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

Performs the conversion.
