Struct Operator 

pub struct Operator { /* private fields */ }

Who asked, and what established it.

Deserialization is a constructor, and it takes the same door

#[serde(try_from)] rather than a derived Deserialize, because a derive reaches the private field directly and would admit the empty name authenticated exists to refuse. This value arrives from a store row and from a journal record far more often than from a constructor call, and a blank actor read back out of either is an act on record with nobody attached. A type that documents an invariant while deriving Deserialize enforces it on the rare path and not on the ones an attacker or a damaged row takes.

Implementations

impl Operator

pub const MAX_LEN: usize = 256

The longest an actor name may be.

pub fn authenticated(actor: impl Into<String>) -> Result<Self, OperatorError>

An actor an authenticator named.

The caller is asserting that this name came from a verified credential rather than from anything the requester supplied. Nothing here can check that, which is why it is a named constructor: a reviewer reading a call site sees the claim being made.

Errors

OperatorError when the name is empty or over MAX_LEN.

pub fn asserted(actor: impl Into<String>) -> Result<Self, OperatorError>

An actor somebody with the store typed.

Errors

OperatorError when the name is empty or over MAX_LEN.

pub fn connected(actor: impl Into<String>) -> Result<Self, OperatorError>

The party on an accepted connection, named by the channel it arrived on.

Errors

OperatorError when the name is empty or over MAX_LEN.

pub fn from_parts( actor: impl Into<String>, basis: &str, ) -> Result<Self, OperatorError>

Rebuild one from the two columns a store keeps.

The one place a stored pair becomes a value, so four backends’ decoders cannot drift on what an unknown basis means. Each caller frames the failure with its own table name; the rule itself lives here.

Errors

OperatorError when the name is unusable or the basis is one this build does not know.

pub fn actor(&self) -> &str

The name on the record.

pub const fn basis(&self) -> Basis

What established it.

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Operator

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Operator

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

alice (authenticated).

The basis is in the rendering rather than beside it because this string reaches listings and refusal messages, and the place a reader meets the name is the place they need to know what it is worth.

impl Eq for Operator

impl From<&Operator> for ActorView

fn from(op: &Operator) -> Self

Converts to this type from the input type.

impl Hash for Operator

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 JsonSchema for Operator

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Ord for Operator

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Operator

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Operator

fn partial_cmp(&self, other: &Self) -> 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 Operator

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
