Implementations

impl NameHeuristics

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

Parse from a TOML string.

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

Load from a TOML file on disk.

pub fn load_default() -> Self

Load the default heuristics.

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

pub fn infer_kind(&self, name: &str) -> Option<FieldKind>

Try to match a column name against the rules. Returns None when no rule matches, signalling the caller to fall back to value sampling.
