Trait elastic_types::boolean::mapping::BooleanMapping

[src]
pub trait BooleanMapping where
Self: Default, { fn boost() -> Option<f32> { ... } fn doc_values() -> Option<bool> { ... } fn index() -> Option<bool> { ... } fn null_value() -> Option<bool> { ... } fn store() -> Option<bool> { ... } }
The base requirements for mapping a boolean
type.
Custom mappings can be defined by implementing BooleanMapping
.
Examples
Define a custom BooleanMapping
:
#[derive(Default)] struct MyBooleanMapping; impl BooleanMapping for MyBooleanMapping { //Overload the mapping functions here fn boost() -> Option<f32> { Some(1.5) } }
This will produce the following mapping:
{ "type": "boolean", "boost": 1.5 }
Provided Methods
fn boost() -> Option<f32>
Field-level index time boosting. Accepts a floating point number, defaults to 1.0
.
fn doc_values() -> Option<bool>
Should the field be stored on disk in a column-stride fashion,
so that it can later be used for sorting, aggregations, or scripting?
Accepts true
(default) or false
.
fn index() -> Option<bool>
Should the field be searchable? Accepts not_analyzed
(default) and no
.
fn null_value() -> Option<bool>
Accepts a string value which is substituted for any explicit null values.
Defaults to null
, which means the field is treated as missing.
fn store() -> Option<bool>
Whether the field value should be stored and retrievable separately from the _source
field.
Accepts true
or false
(default).
