can be useful to print out a human readable
representation of this tree when debugging a given score.
Implementations§
source§impl Explanation
impl Explanation
sourcepub fn new_with_string(description: String, value: Score) -> Explanation
pub fn new_with_string(description: String, value: Score) -> Explanation
Creates a new explanation object.
sourcepub fn new(description: &'static str, value: Score) -> Explanation
pub fn new(description: &'static str, value: Score) -> Explanation
Creates a new explanation object.
sourcepub fn add_detail(&mut self, child_explanation: Explanation)
pub fn add_detail(&mut self, child_explanation: Explanation)
Add some detail, explaining some part of the current node formula.
Details are treated as child of the current node.
sourcepub fn add_context(&mut self, context: String)
pub fn add_context(&mut self, context: String)
Adds some extra context to the explanation.
sourcepub fn add_const(&mut self, name: &'static str, value: Score)
pub fn add_const(&mut self, name: &'static str, value: Score)
Shortcut for self.details.push(Explanation::new(name, value));
sourcepub fn to_pretty_json(&self) -> String
pub fn to_pretty_json(&self) -> String
Returns an indented json representation of the explanation tree for debug usage.
