pub fn new(value: impl Into<String>) -> Self

Create a new tag.

pub fn entity(entity: &str) -> Self

Create an entity-type tag.

pub fn record<I: Display>(entity: &str, id: I) -> Self

Create a record-specific tag.

pub fn tenant(tenant: &str) -> Self

Create a tenant tag.

pub fn query(name: &str) -> Self

Trait Implementations

impl Clone for EntityTag

fn clone(&self) -> EntityTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityTag

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

Formats the value using the given formatter.

impl Display for EntityTag

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

Formats the value using the given formatter.

impl From<&str> for EntityTag

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for EntityTag

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for EntityTag

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 EntityTag

fn eq(&self, other: &EntityTag) -> 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.
