Implementations

impl Provider

pub fn from_id_str(s: &str) -> Option<Self>

Parse a provider id string back to the typed variant. Returns None if the string doesn’t match any known provider. Prefer this over string conversion to avoid panics.

pub fn as_str(self) -> &'static str

String identifier matching [ProviderAdapter::id].

Trait Implementations

impl Clone for Provider

fn clone(&self) -> Provider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Provider

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

Formats the value using the given formatter.

impl Default for Provider

fn default() -> Provider

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Provider

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Provider

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 PartialEq for Provider

fn eq(&self, other: &Provider) -> 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 Serialize for Provider

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Provider

impl Eq for Provider
