Struct ConfigBuilder 

pub struct ConfigBuilder { /* private fields */ }

Fluent builder for Config.

Example

use drain3::Config;
let cfg = Config::builder()
    .depth(5)
    .similarity_threshold(0.6)
    .build()
    .unwrap();

Implementations

impl ConfigBuilder

pub fn new() -> Self

Create a builder with the same defaults as Config::default().

pub fn depth(self, v: usize) -> Self

Prefix tree depth. Must be >= 3.

pub fn similarity_threshold(self, v: f64) -> Self

Fraction of tokens that must match for a line to join a cluster during training.

pub fn match_threshold(self, v: f64) -> Self

Fraction of tokens that must match for a line to be considered a match.

pub fn max_children(self, v: usize) -> Self

Max children per inner node. One slot is reserved for the param catch-all.

pub fn max_tokens(self, v: usize) -> Self

Max tokens per line. Lines with more tokens are skipped.

pub fn max_bytes(self, v: usize) -> Self

Max bytes per line. Lines longer than this are skipped.

pub fn max_clusters(self, v: usize) -> Self

Max clusters. 0 = unlimited.

pub fn param_string(self, v: impl Into<String>) -> Self

Placeholder string for param tokens (default: <*>).

pub fn parametrize_numeric_tokens(self, v: bool) -> Self

Whether numeric tokens are automatically parameterized during tree insertion.

pub fn extra_delimiters(self, v: Vec<String>) -> Self

Additional delimiter strings to replace with spaces before tokenization.

pub fn enable_match_prefilter(self, v: bool) -> Self

Enable the first/last token prefilter optimization for matching.

pub fn build(self) -> Result<Config, Error>

Build and validate the configuration.

Trait Implementations

impl Clone for ConfigBuilder

fn clone(&self) -> ConfigBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigBuilder

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

Formats the value using the given formatter.

impl Default for ConfigBuilder

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ConfigBuilder

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
