Enum relay_pii::SelectorSpec

pub enum SelectorSpec {
    And(Vec<SelectorSpec>),
    Or(Vec<SelectorSpec>),
    Not(Box<SelectorSpec>),
    Path(Vec<SelectorPathItem>),
}

A selector that can match paths of processing states.

To use a a selector, you most likely want to check whether it matches the path of a ProcessingState. For this you turn the state into a Path using ProcessingState::path and call SelectorSpec::matches_path, which will iterate through the path items in the processing state and check whether the selector matches.

Variants

And(Vec<SelectorSpec>)

A selector that matches both of two sub-selectors.

Or(Vec<SelectorSpec>)

A selector that matches either of two sub-selectors.

Not(Box<SelectorSpec>)

A selector that matches all paths that do not match the sub-selector.

Path(Vec<SelectorPathItem>)

A direct path to an item.

Implementations

impl SelectorSpec

pub fn parse_non_legacy(s: &str) -> Result<SelectorSpec, InvalidSelectorError>

Parses a selector from a string without legacy special handling.

pub fn matches_path(&self, path: &Path<'_>) -> bool

Checks if a path matches given selector.

This walks both the selector and the path starting at the end and towards the root to determine if the selector matches the current path.

Trait Implementations

impl Clone for SelectorSpec

fn clone(&self) -> SelectorSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SelectorSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectorSpec

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SelectorSpec

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

Formats the value using the given formatter.

impl From<ValueType> for SelectorSpec

fn from(value_type: ValueType) -> Self

Converts to this type from the input type.

impl FromStr for SelectorSpec

type Err = InvalidSelectorError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for SelectorSpec

fn cmp(&self, other: &SelectorSpec) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SelectorSpec

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SelectorSpec

fn partial_cmp(&self, other: &SelectorSpec) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SelectorSpec

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SelectorSpec
