Implementations

impl FrameColumn

pub fn as_wildcard_mut(&mut self) -> Option<&mut String>

Optionally returns mutable references to the inner fields if this is a FrameColumn::Wildcard, otherwise None

pub fn as_wildcard(&self) -> Option<&String>

Optionally returns references to the inner fields if this is a FrameColumn::Wildcard, otherwise None

pub fn into_wildcard(self) -> Result<String, Self>

Returns the inner fields if this is a FrameColumn::Wildcard, otherwise returns back the enum in the Err case of the result

pub fn as_single_mut(&mut self) -> Option<(&mut Option<Ident>, &mut usize)>

Optionally returns mutable references to the inner fields if this is a FrameColumn::Single, otherwise None

pub fn as_single(&self) -> Option<(&Option<Ident>, &usize)>

Optionally returns references to the inner fields if this is a FrameColumn::Single, otherwise None

pub fn into_single(self) -> Result<(Option<Ident>, usize), Self>

Returns the inner fields if this is a FrameColumn::Single, otherwise returns back the enum in the Err case of the result

Trait Implementations

impl Clone for FrameColumn

fn clone(&self) -> FrameColumn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameColumn

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FrameColumn

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<FrameColumn> for FrameColumn

fn eq(&self, other: &FrameColumn) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FrameColumn

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

Serialize this value into the given Serde serializer.
