Implementations

impl ConcatSource

pub fn new<S, T>(sources: S) -> Self

where T: Source + 'static, S: IntoIterator<Item = T>,

Create a ConcatSource with Sources.

pub fn add<S: Source + 'static>(&mut self, source: S)

Add a Source to concat.

Trait Implementations

impl Clone for ConcatSource

fn clone(&self) -> ConcatSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConcatSource

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

Formats the value using the given formatter.

impl Default for ConcatSource

fn default() -> ConcatSource

Returns the “default value” for a type.

impl Hash for ConcatSource

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 PartialEq for ConcatSource

fn eq(&self, other: &Self) -> 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 Source for ConcatSource

fn source(&self) -> Cow<'_, str>

Get the source code.

fn buffer(&self) -> Cow<'_, [u8]>

Get the source buffer.

fn size(&self) -> usize

Get the size of the source.

fn map(&self, options: &MapOptions) -> Option<SourceMap>

Get the SourceMap.

fn to_writer(&self, writer: &mut dyn Write) -> Result<()>

Writes the source into a writer, preferably a std::io::BufWriter<std::io::Write>.

fn update_hash(&self, state: &mut dyn Hasher)

Update hash based on the source.

impl StreamChunks for ConcatSource

fn stream_chunks( &self, options: &MapOptions, on_chunk: OnChunk<'_>, on_source: OnSource<'_>, on_name: OnName<'_>, ) -> GeneratedInfo

StreamChunks abstraction
