Enum OneShotError 

#[non_exhaustive]
pub enum OneShotError {
    Parse(ParseError),
    Apply(StrictApplyError),
    NoPatchesFound,
    MultiplePatchesFound(usize),
}

Represents errors that can occur during the high-level patch_content_str() operation.

This enum consolidates all possible failures from the one-shot workflow, including parsing errors, finding the wrong number of patches, or failures during the strict application process.

Example

use mpatch::{patch_content_str, ApplyOptions, OneShotError};

// This diff content contains two patches, which is not allowed by `patch_content_str`.
let multi_patch_diff = r#"
```diff
--- a/file1.txt
+++ b/file1.txt
@@ -1 +1 @@
-a
+b
--- a/file2.txt
+++ b/file2.txt
@@ -1 +1 @@
-c
+d
```
"#;

let options = ApplyOptions::new();
let result = patch_content_str(multi_patch_diff, Some("a\n"), &options);

assert!(matches!(result, Err(OneShotError::MultiplePatchesFound(2))));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Parse(ParseError)

An error occurred while parsing the diff content.

Apply(StrictApplyError)

An error occurred while applying the patch. This includes partial applications.

NoPatchesFound

The provided diff content did not contain any valid patches (Markdown blocks, Unified Diffs, or Conflict Markers).

MultiplePatchesFound(usize)

The provided diff content contained patches for more than one file, which is not supported by this simplified function. Use parse_diffs() and apply_patches_to_dir() for multi-file operations.

Trait Implementations

impl Debug for OneShotError

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

Formats the value using the given formatter.

impl Display for OneShotError

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

Formats the value using the given formatter.

impl Error for OneShotError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ParseError> for OneShotError

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl From<StrictApplyError> for OneShotError

fn from(source: StrictApplyError) -> Self

Converts to this type from the input type.
