Struct DiffOptions 

pub struct DiffOptions {
    pub float_tolerance: Option<f64>,
    pub similarity_threshold: Option<f64>,
}

Configuration options for diff computation

Fields

float_tolerance: Option<f64>

Tolerance for floating-point comparisons. If set, two floats are considered equal if their absolute difference is less than or equal to this value.

similarity_threshold: Option<f64>

Similarity threshold for tree-based element matching in sequences. If set, sequence elements with structural similarity >= this threshold are paired for inline diffing rather than shown as remove+add.

Recommended values: 0.5-0.7. Higher = stricter matching. When None (default), uses exact equality only.

Implementations

impl DiffOptions

pub fn new() -> Self

Create a new DiffOptions with default settings.

pub fn with_float_tolerance(self, tolerance: f64) -> Self

Set the tolerance for floating-point comparisons.

pub fn with_similarity_threshold(self, threshold: f64) -> Self

Set the similarity threshold for tree-based element matching.

When set, sequence elements with structural similarity >= this threshold are paired for inline field-level diffing rather than shown as remove+add.

This uses the cinereus GumTree algorithm to compute structural similarity based on hash matching and Dice coefficient.

Arguments

• threshold - Minimum similarity score (0.0 to 1.0). Recommended: 0.5-0.7.
