Struct RenameAttr

pub struct RenameAttr {
    pattern: Option<RenamePattern>,
}

A pattern for use in rename attributes, like #[diplomat::abi_rename]

This can be parsed from a string, typically something like icu4x_{0}. It can have up to one {0} for replacement.

In the future this may support transformations like to_camel_case, etc, probably specified as a list like #[diplomat::abi_rename("foo{0}", to_camel_case)]

Fields

pattern: Option<RenamePattern>

Implementations

impl RenameAttr

pub fn apply<'a>(&'a self, name: Cow<'a, str>) -> Cow<'a, str>

Apply all renames to a given string

fn is_empty(&self) -> bool

Whether this rename is empty and will perform no changes

pub(crate) fn extend(&mut self, other: &Self)

pub(crate) fn attrs_for_inheritance( &self, context: AttrInheritContext, is_abi_rename: bool, ) -> Self

Get a copy of these attributes for use in inheritance, masking out things that should not be inherited

fn from_pattern(s: &str) -> Self

From a replacement pattern, like “icu4x_{0}”. Can have up to one {0} in it for substitution.

pub(crate) fn from_meta(meta: &Meta) -> Result<Self, &'static str>

Trait Implementations

impl Clone for RenameAttr

fn clone(&self) -> RenameAttr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RenameAttr

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

Formats the value using the given formatter.

impl Default for RenameAttr

fn default() -> RenameAttr

Returns the “default value” for a type.

impl Hash for RenameAttr

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 RenameAttr

fn cmp(&self, other: &RenameAttr) -> 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 RenameAttr

fn eq(&self, other: &RenameAttr) -> 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 RenameAttr

fn partial_cmp(&self, other: &RenameAttr) -> 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.

impl Serialize for RenameAttr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for RenameAttr

impl StructuralPartialEq for RenameAttr
