Struct Normalizer 

pub struct Normalizer {
    pub float_tolerance: f64,
    pub timestamps: bool,
    pub numeric_strings: bool,
}

How values are canonicalised before hashing and comparing, so two backends’ spellings of the same value agree.

Fields

float_tolerance: f64

Round floats to this absolute tolerance before comparing (0 = exact).

timestamps: bool

Parse strings that look like timestamps (RFC 3339, or YYYY-MM-DD HH:MM:SS[.fff]) and compare them as UTC microseconds.

numeric_strings: bool

Treat a string holding a number ("42", "1.5") as that number.

Implementations

impl Normalizer

pub fn validate(&self) -> Result<(), FaucetError>

Fail-fast validation: a finite, non-negative tolerance.

pub fn canonical(&self, v: Option<&Value>) -> String

The canonical text of one value. Missing and null both canonicalise to the same token, so a column absent on one side equals null on the other.

Trait Implementations

impl Clone for Normalizer

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Normalizer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Normalizer

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Normalizer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Normalizer

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Normalizer

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Normalizer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
