Module common

Available on crate feature __common only.

Modules

• collections
• comments
• errors
• input
• iter
• pass
  This module reexports items from swc_visit with some swc-specific traits.
• plugin
• serializerDeprecated
• source_map
  The SourceMap tracks all the source code used within a single crate.
• sync
  This module defines types which are thread safe if cfg!(feature = "concurrent") is true.
• util

Macros

• chain
  Chains multiple visitor.
• impl_stable_hash_via_hash

Structs

• ArchivedBytePos
  An archived BytePos
• ArchivedCharPos
  An archived CharPos
• ArchivedMultiSpan
  An archived MultiSpan
• ArchivedSourceFile
  An archived SourceFile
• ArchivedSourceFileAndBytePos
  An archived SourceFileAndBytePos
• ArchivedSpan
  An archived Span
• BytePos
  A byte offset. Keep this small (currently 32-bits), as AST contains a lot of them.
• CharPos
  A character offset. Because of multibyte utf8 characters, a byte offset is not equivalent to a character offset. The SourceMap will convert BytePos values to CharPos values as necessary.
• FileLines
  A struct to represent lines of a source file.
• FilePathMapping
• Globals
• LineCol
  Used to create a .map file.
• Loc
  A source code location used for error reporting.
• LocWithOpt
  A source code location used as the result of lookup_char_pos_adj
• Mark
  A mark is a unique id associated with a macro expansion.
• MultiSpan
  A collection of spans. Spans have two orthogonal attributes:
• SourceFile
  A single source in the SourceMap.
• SourceFileAndBytePos
• SourceFileAndLine
• SourceMap
  The interner for spans.
• Span
  Spans represent a region of code, used for error reporting.
• SyntaxContext
  A SyntaxContext represents a chain of macro expansions (represented by marks).

Enums

• ArchivedFileName
  An archived FileName
• ArchivedSpanLinesError
  An archived SpanLinesError
• ArchivedSpanSnippetError
  An archived SpanSnippetError
• FileName
• SpanLinesError
• SpanSnippetError

Constants

• DUMMY_SP
  Dummy span, both position and length are zero, syntax context is zero as well.
• NO_EXPANSION

Statics

• GLOBALS
  Storage for span hygiene data.

Traits

• AstNode
  A trait for ast nodes.
• EqIgnoreSpan
  Derive with #[derive(EqIgnoreSpan)].
• FileLoader
  An abstraction over the fs operations used by the Parser.
• SourceMapper
• Spanned
  Derive
• TypeEq
  Derive with #[derive(TypeEq)].

Type Aliases

• SourceMapperDyn

Attribute Macros

• ast_node
  Alias for #[derive(Spanned, Fold, Clone, Debug, PartialEq)] for a struct and #[derive(Spanned, Fold, Clone, Debug, PartialEq, FromVariant)] for an enum.
• ast_serde
  Derives serde::Serialize and serde::Deserialize.

Derive Macros

• DeserializeEnum
  Derives serde::Deserialize which is aware of tag based deserialization.
• EqIgnoreSpan
  Derives swc_common::EqIgnoreSpan.
• FromVariant
  Derives [From] for all variants. This only supports an enum where every variant has a single field.
• Spanned
  Derives [swc_common::Spanned]. See [swc_common::Spanned] for documentation.
• TypeEq
  Derives swc_common::TypeEq.
