Struct ProjectValue 

Source 
pub struct ProjectValue<T> { /* private fields */ }
Expand description

A typed value together with every source span that contributed to it during merging.

Implementations§

Source§

impl<T> ProjectValue<T>

Source

pub const fn value(&self) -> &T

Returns the typed effective value.

Source

pub const fn provenance(&self) -> &MergeProvenance

Returns the merge operation and contributing spans in processing order.

Source

pub fn effective_source(&self) -> Option<SourceSpan>

Returns the most recent source contributing to this value.

Source

pub const fn is_sensitive(&self) -> bool

Reports whether this value contains sensitive interpolation output.

Source

pub fn into_value(self) -> T

Removes the provenance wrapper and returns the typed value.
