Struct OwnedValuePath 

pub struct OwnedValuePath {
    pub segments: Vec<OwnedSegment>,
}

A lookup path.

Fields

segments: Vec<OwnedSegment>

Implementations

impl OwnedValuePath

pub fn is_root(&self) -> bool

pub fn root() -> Self

pub fn push_field(&mut self, field: &str)

pub fn push_segment(&mut self, segment: OwnedSegment)

pub fn push_front_field(&mut self, field: &str)

pub fn push_front_segment(&mut self, segment: OwnedSegment)

pub fn with_field_appended(&self, field: &str) -> Self

pub fn with_field_prefix(&self, field: &str) -> Self

pub fn with_segment_prefix(&self, segment: OwnedSegment) -> Self

pub fn push_index(&mut self, index: isize)

pub fn with_index_appended(&self, index: isize) -> Self

pub fn single_field(field: &str) -> Self

pub fn to_alternative_components(&self, limit: usize) -> Option<Vec<&str>>

Create the possible fields that can be followed by this lookup.

The limit specifies the limit of the path depth we are interested in. Metrics is only interested in fields that are up to 3 levels deep (2 levels + 1 to check it terminates).

eg, .tags.nork.noog will never be an accepted path so we don’t need to spend the time collecting it.

pub fn push(&mut self, segment: OwnedSegment)

impl Ord for OwnedValuePath

fn cmp(&self, other: &OwnedValuePath) -> Ordering

This method returns an Ordering between self and other.
