[−][src]Struct tantivy::query::Explanation
Object describing the score of a given document. It is organized in trees.
.to_pretty_json()
can be useful to print out a human readable
representation of this tree when debugging a given score.
Methods
impl Explanation
[src]
pub fn new<T: ToString>(description: T, value: f32) -> Explanation
[src]
Creates a new explanation object.
pub fn value(&self) -> f32
[src]
Returns the value associated to the current node.
pub fn add_detail(&mut self, child_explanation: Explanation)
[src]
Add some detail, explaining some part of the current node formula.
Details are treated as child of the current node.
pub fn add_const<T: ToString>(&mut self, name: T, value: f32)
[src]
Shortcut for self.details.push(Explanation::new(name, value));
pub fn to_pretty_json(&self) -> String
[src]
Returns an indented json representation of the explanation tree for debug usage.
