Module brush_parser::ast

Defines the Abstract Syntax Tree (ast) for shell programs. Includes types and utilities for manipulating the AST.

Structs

• AndOrList
  Represents a sequence of command pipelines connected by boolean operators.
• ArithmeticCommand

• Assignment
  Encapsulates an assignment declaration.
• BraceGroupCommand
  A brace group, which groups commands together.
• CaseClauseCommand
  A case clause, which selects a command based on a value and a set of pattern-based filters.
• CaseItem
  An individual matching case item in a case clause.
• CommandPrefix
  Represents a prefix to a simple command.
• CommandSuffix
  Represents a suffix to a simple command; a word argument, declaration, or I/O redirection.
• CompoundList
  A sequence of commands.
• CompoundListItem
  An element of a compound command list.
• DoGroupCommand
  A do group, which groups commands together.
• ElseClause
  Represents the else clause of a conditional command.
• ForClauseCommand
  A for clause, which loops over a set of values.
• FunctionBody
  Encapsulates the body of a function definition.
• FunctionDefinition
  Encapsulates the definition of a shell function.
• IfClauseCommand
  An if clause, which conditionally executes a command.
• IoHereDocument
  Represents an I/O here document.
• Pipeline
  A pipeline of commands, where each command’s output is passed as standard input to the command that follows it.
• Program
  Represents a complete shell program.
• RedirectList
  A list of I/O redirections to be applied to a command.
• SimpleCommand
  Represents the invocation of a simple command.
• SubshellCommand
  A subshell, which executes commands in a subshell.
• UnexpandedArithmeticExpr
  Encapsulates an unparsed arithmetic expression.
• WhileOrUntilClauseCommand
  A while or until clause, whose looping is controlled by a condition.
• Word
  Represents a shell word.
