Struct Expression

pub struct Expression {
    pub collection: String,
    pub expression: String,
}

Expression represents a conditional expression that refines the scope of a RoleBinding.

Fields

collection: String

The collection the expression applies to.

expression: String

The actual expression string. The syntax and semantics of this string are context-dependent.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Default for Expression

fn default() -> Expression

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Expression

fn deserialize<__D>( __deserializer: __D, ) -> Result<Expression, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'s> Instance<'s> for Expression

fn name(&self) -> SmolStr

Returns the name of a instance

fn as_inst(&self) -> &(dyn Instance<'s> + 's)

impl Message for Expression

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Expression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'s> StructInstance<'s> for Expression

fn get_value<'v>(&'v self, field: &str) -> Option<CowValue<'v, 's>>

where 's: 'v,

Returns a reference to a field in a struct

fn values<'v>(&'v self) -> HashMap<SmolStr, CowValue<'v, 's>>

Returns a HashMap containing all the attributes of the instance.

fn update<'v>( &'v mut self, instance: &'v (dyn StructInstance<'s> + 's), field_mask: Option<&FieldMask>, replace_repeated: bool, ) -> Result<(), Error>

Updates an instance based on the instance passed in. If a field mask is specified only the fields passed with the mask will be updated.

fn boxed_clone(&self) -> Box<dyn StructInstance<'s> + 's>

Returns a clone of the instance in a Box.

fn into_boxed_instance(self: Box<Expression>) -> Box<dyn Instance<'s> + 's>

Casts Self to a Box<dyn Instance>

impl<'s> Typed<'s> for Expression

fn ty() -> ValueTy

fn as_value<'t>(&'t self) -> Value<'t, 's>

where 's: 't,
