Crate rsexpr

rsexpr

Small and simple S-expression parsing and manipulation with support for square-bracketed groups and strings. Used by syntastica for processing tree-sitter queries.

Have a look at Sexpr, OwnedSexpr, from_slice, and from_slice_multi for more information.

Features

• comments — Include comments in the parsed tree and pretty-printed output

• docs — Meant to be enabled when building docs

Structs

• OwnedSexprs
  A thin wrapper around Vec<OwnedSexpr> with its own Display implementation. See OwnedSexpr for more information.
• Sexprs
  A thin wrapper around Vec<Sexpr> with its own Display implementation. See Sexpr for more information.

Enums

• Error
  The crate error type.
• OwnedSexpr
  An owned version of Sexpr. You can convert to and from Sexpr using the From trait.
• ParenKind
  A kind of parentheses. Used in Error::MissingClosingParen and Error::ExtraClosingParen to indicate the kind of parentheses that caused the error.
• Sexpr
  A single node of the tree. The Atom and String variants reference the input slice. For an owned version have a look at OwnedSexpr.

Functions

• from_slice
  Parse a Sexpr from bytes. This fails if there is more than one S-expression in the input. To allow an arbitrary amount of S-expressions, have a look at from_slice_multi.
• from_slice_multi
  Parse multiple Sexprs from bytes. To only parse a single one, have a look at from_slice.

Type Definitions

• Result
  The default result type. The error variant is a vector of Errors
