Struct ComponentName

pub struct ComponentName { /* private fields */ }

An import or export name in the component model which is backed by T, which defaults to String.

This name can be either:

• a plain label or “kebab string”: a-b-c
• a plain method name : [method]a-b.c-d
• a plain static method name : [static]a-b.c-d
• a plain constructor: [constructor]a-b
• an interface name: wasi:cli/reactor@0.1.0
• a dependency name: locked-dep=foo:bar/baz
• a URL name: url=https://..
• a hash name: integrity=sha256:...

Equality and hashing

Note that this type the [method]... and [static]... variants are considered equal and hash to the same value. This enables disallowing clashes between the two where method name overlap cannot happen.

Implementations

impl ComponentName

pub fn new( name: &str, offset: usize, ) -> Result<ComponentName, BinaryReaderError>

Attempts to parse name as a valid component name, returning Err if it’s not valid.

pub fn new_with_features( name: &str, offset: usize, features: WasmFeatures, ) -> Result<ComponentName, BinaryReaderError>

Attempts to parse name as a valid component name, returning Err if it’s not valid.

features can be used to enable or disable validation of certain forms of supported import names.

pub fn kind(&self) -> ComponentNameKind<'_>

Returns the ComponentNameKind corresponding to this name.

pub fn as_str(&self) -> &str

Returns the raw underlying name as a string.

Trait Implementations

impl Clone for ComponentName

fn clone(&self) -> ComponentName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentName

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

Formats the value using the given formatter.

impl Display for ComponentName

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

Formats the value using the given formatter.

impl From<ComponentName> for String

fn from(name: ComponentName) -> String

Converts to this type from the input type.

impl Hash for ComponentName

fn hash<H>(&self, hasher: &mut H)

where H: Hasher,

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 ComponentName

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

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

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