Struct ApplyOptionsBuilder 

pub struct ApplyOptionsBuilder { /* private fields */ }

Creates a new builder for ApplyOptions.

This provides a classic builder pattern for constructing an ApplyOptions struct, which can be useful when the configuration is built conditionally or comes from multiple sources.

Example

use mpatch::ApplyOptions;

let mut builder = ApplyOptions::builder();
let is_dry_run = true;

if is_dry_run {
    builder = builder.dry_run(true);
}

let options = builder.fuzz_factor(0.8).build();

assert_eq!(options.dry_run, true);
assert_eq!(options.fuzz_factor, 0.8);

Implementations

impl ApplyOptionsBuilder

pub fn dry_run(self, dry_run: bool) -> Self

Sets the dry_run flag for the patch operation.

If true, no files will be modified. Instead, a diff of the proposed changes will be generated and returned in PatchResult. This is useful for previewing changes before they are applied.

Example

let options = ApplyOptions::builder()
    .dry_run(true) // Enable dry-run mode
    .build();
assert!(options.dry_run);

pub fn fuzz_factor(self, fuzz_factor: f32) -> Self

Sets the similarity threshold for fuzzy matching.

The fuzz_factor is a value between 0.0 and 1.0 that determines how closely a block of text in the target file must match a hunk’s context to be considered a “fuzzy match”. A higher value requires a closer match. Setting it to 0.0 disables fuzzy matching entirely, requiring an exact match.

Example

// Require a very high similarity (90%) for a fuzzy match to be accepted.
let options = ApplyOptions::builder().fuzz_factor(0.9).build();
assert_eq!(options.fuzz_factor, 0.9);

pub fn build(self) -> ApplyOptions

Builds the ApplyOptions struct from the builder’s configuration.

This method consumes the builder and returns a final ApplyOptions instance. Any options not explicitly set on the builder will fall back to their default values.

Example

let options = ApplyOptions::builder()
    .dry_run(true) // Finalize the configuration
    .fuzz_factor(0.8)
    .build();

assert!(options.dry_run);
assert_eq!(options.fuzz_factor, 0.8);
