fallback_kind: FieldKind

Implementations

impl ValuePatterns

pub fn from_toml_str(s: &str) -> Result<Self, ZerError>

Parse from a TOML string. Returns Err if any regex is invalid.

pub fn from_file(path: &Path) -> Result<Self, ZerError>

Load from a TOML file on disk.

pub fn load_default() -> Self

Load the default patterns.

Checks ZER_VALUE_PATTERNS env var first; if set and loadable, uses that file. Otherwise falls back to the embedded heuristics_values.toml.

pub fn infer_kind(&self, samples: &[&str]) -> FieldKind

Infer a FieldKind from a slice of sampled text values.

Evaluates patterns in order; returns the first match. Falls back to fallback_kind (typically FreeText) when nothing matches.

Trait Implementations

impl Debug for ValuePatterns

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

Formats the value using the given formatter.
