Struct Checks 

pub struct Checks { /* private fields */ }

Fluent builder for heuristic validation checks.

This builder accumulates checks and implements Validate to score text based on how many checks pass. Weights determine the contribution of each check to the final score.

Stack Allocation

Checks are stored in a SmallVec with inline capacity for common cases, avoiding heap allocation for typical usage patterns.

Implementations

impl Checks

pub fn new() -> Self

Create a new empty checks builder.

pub fn require(self, pattern: impl Into<String>) -> Self

Require a substring pattern to be present.

The check fails if the text does not contain the pattern.

pub fn require_weighted(self, pattern: impl Into<String>, weight: f64) -> Self

Require a substring pattern with custom weight.

pub fn require_all<I, S>(self, patterns: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Require multiple substring patterns to be present.

Equivalent to calling .require() for each pattern.

pub fn require_all_weighted<I, S>(self, patterns: I, weight: f64) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Require multiple substring patterns with custom weight.

pub fn forbid(self, pattern: impl Into<String>) -> Self

Forbid a substring pattern.

The check fails if the text contains the pattern.

pub fn forbid_weighted(self, pattern: impl Into<String>, weight: f64) -> Self

Forbid a substring pattern with custom weight.

pub fn forbid_all<I, S>(self, patterns: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Forbid multiple substring patterns.

Equivalent to calling .forbid() for each pattern.

pub fn forbid_all_weighted<I, S>(self, patterns: I, weight: f64) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Forbid multiple substring patterns with custom weight.

pub fn regex(self, pattern: impl Into<String>) -> Self

Require a regex pattern to match.

The regex is lazily compiled on first use.

pub fn regex_weighted(self, pattern: impl Into<String>, weight: f64) -> Self

Require a regex pattern with custom weight.

pub fn regex_all<I, S>(self, patterns: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Require multiple regex patterns to match.

Equivalent to calling .regex() for each pattern.

pub fn regex_all_weighted<I, S>(self, patterns: I, weight: f64) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Require multiple regex patterns with custom weight.

pub fn min_len(self, n: usize) -> Self

Require minimum text length.

pub fn min_len_weighted(self, n: usize, weight: f64) -> Self

Require minimum text length with custom weight.

pub fn max_len(self, n: usize) -> Self

Require maximum text length.

pub fn max_len_weighted(self, n: usize, weight: f64) -> Self

Require maximum text length with custom weight.

pub fn max_errors(self, n: usize) -> Self

Limit the number of error-like lines.

Counts lines containing “error”, “Error”, or “ERROR”.

pub fn pred(self, name: &'static str, f: fn(&str) -> bool) -> Self

Add a custom predicate check.

The predicate receives the text and returns true if it passes.

pub fn pred_weighted( self, name: &'static str, f: fn(&str) -> bool, weight: f64, ) -> Self

Add a custom predicate check with custom weight.

pub fn weight(self, w: f64) -> Self

Set the weight for the most recently added check.

Panics

Panics if no checks have been added yet.

pub fn feedback(self, msg: impl Into<String>) -> Self

Set custom feedback for the most recently added check.

pub fn require_if(self, cond: bool, pattern: impl Into<String>) -> Self

Conditionally require a substring pattern.

pub fn forbid_if(self, cond: bool, pattern: impl Into<String>) -> Self

Conditionally forbid a substring pattern.

pub fn python(self) -> Self

Preset checks for Python code.

pub fn rust(self) -> Self

Preset checks for Rust code.

pub fn json(self) -> Self

Preset checks for valid JSON.

pub fn yaml(self) -> Self

Preset checks for YAML structure.

pub fn sql(self) -> Self

Preset checks for SQL statements.

Trait Implementations

impl Clone for Checks

fn clone(&self) -> Checks

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Checks

fn default() -> Self

Returns the “default value” for a type.

impl Validate for Checks

fn validate(&self, text: &str) -> Score<'static>

Validate the given text and return a score.

fn name(&self) -> &'static str

Get the name of this validator (for logging/debugging).
