Module lexpr::print

Converting S-expression values into text.

Terminology

The process of serializing S-expressions to their textual representation is referred to “writing” in Lisp. To avoid confusion with Rust’s Write trait, lexpr uses “printing” instead.

Structs

• CustomizedFormatter
  A formatter which can be tuned with regards to S-expressions representation.
• DefaultFormatter
  This structure compacts a S-expression value on a single line, using the default representation, which is similar to Scheme.
• Options
  Options for printing S-expressions.
• Printer
  A printer for S-expression values.

Enums

• BoolSyntax
  How to print boolean values.
• BytesSyntax
  How to print byte vectors.
• CharEscape
  Represents a character escape code in a type-safe manner.
• CharSyntax
  Indicates the syntax for characters.
• KeywordSyntax
  Indicates a syntax of keywords.
• NilSyntax
  How to print the special nil value.
• StringSyntax
  Indicates the syntax for strings.
• VectorSyntax
  How to print vectors.
• VectorType
  Different vector types

Traits

• Formatter
  This trait abstracts away serializing the S-expression pieces, which allows the implementer to optionally pretty print the S-expression output, as well as to allow customizing the printing for various S-expression “dialects”.

Functions

• to_string

• to_string_custom
  Serialize the given value an S-expression string.
• to_vec
  Serialize the given value as byte vector containing S-expression text, using the default printer options.
• to_vec_custom
  Serialize the given value as byte vector containing S-expression text.
• to_writer
  Serialize the given value value as S-expression text into the IO stream, using the default printer options.
• to_writer_custom
  Serialize the given value value as S-expression text into the IO stream.
