Enum DriverChoice

pub enum DriverChoice {
    BuiltIn(BuiltinDriver),
    Index(usize),
}

The selection of the driver to use by a resource obtained with Platform::prepare_merge().

If available, an index into the drivers field to access more diff-related information of the driver for items at the given path, as previously determined by git-attributes.

• merge is set
  • Use the BuiltinDriver::Text
• -merge is unset
  • Use the BuiltinDriver::Binary
• !merge is unspecified
  • Use Options::default_driver or BuiltinDriver::Text.
• merge=name
  • Search for a user-configured or built-in driver called name.
  • If not found, silently default to BuiltinDriver::Text

Note that drivers are queried even if there is no object available.

Variants

BuiltIn(BuiltinDriver)

Use the given built-in driver to perform the merge.

Index(usize)

Use the user-provided driver program using the index into the platform drivers array.

Trait Implementations

impl Clone for DriverChoice

fn clone(&self) -> DriverChoice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DriverChoice

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

Formats the value using the given formatter.

impl Default for DriverChoice

fn default() -> Self

Returns the “default value” for a type.

impl Hash for DriverChoice

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DriverChoice

fn cmp(&self, other: &DriverChoice) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DriverChoice

fn eq(&self, other: &DriverChoice) -> 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.

impl PartialOrd for DriverChoice

fn partial_cmp(&self, other: &DriverChoice) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
