Enum ValidationRule 

#[non_exhaustive]
pub enum ValidationRule {
    Pattern(Regex),
    Length(usize),
    LengthRange {
        min: usize,
        max: usize,
    },
    Checksum(ChecksumType),
    NumericRange {
        min: f64,
        max: f64,
    },
    Enum(Vec<String>),
    All(Vec<ValidationRule>),
}

Validation rule for an operator parameter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Pattern(Regex)

Pattern matching (pre-compiled regex)

Length(usize)

Exact length

LengthRange

Min and max length

Fields

min: usize

Minimum allowed length (inclusive).

max: usize

Maximum allowed length (inclusive).

Checksum(ChecksumType)

Checksum algorithm

NumericRange

Range of numeric values

Fields

min: f64

Minimum allowed numeric value (inclusive).

max: f64

Maximum allowed numeric value (inclusive).

Enum(Vec<String>)

Value must be one of these options

All(Vec<ValidationRule>)

Composite rule (all must pass)

Implementations

impl ValidationRule

pub fn validate(&self, value: &str) -> Result<()>

Validate a string value against this rule.

Errors

Returns FraiseQLError::Validation if the value fails the validation rule, or if the pattern is an invalid regex.

pub fn from_json(value: &Value) -> Result<Self>

Parse validation rules from JSON (compiled from TOML).

Errors

Returns FraiseQLError::Validation if the JSON structure does not match any known validation rule format.

Panics

Cannot panic: the internal .expect("len checked == 1") is only reached after verifying rules.len() == 1.

Trait Implementations

impl Clone for ValidationRule

fn clone(&self) -> ValidationRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationRule

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

Formats the value using the given formatter.
