Struct TransformApplier 

pub struct TransformApplier;

Applies pattern-based transformations to source code.

Implementations

impl TransformApplier

pub fn apply( source: &str, pattern: &Pattern, matches: &[Match], ) -> Result<String>

Apply a pattern transformation to source, replacing every occurrence described by matches with the after_template (with bindings substituted).

Errors

Returns CodemodError::Transform if a replacement cannot be constructed (e.g. a variable binding is missing).

pub fn generate_diff( file_path: &str, original: &str, transformed: &str, ) -> String

Generate a unified diff between the original and transformed source.

The output follows the standard unified diff format and is suitable for display or writing to a .patch file.
