Struct full_moon::ast::Ast [−][src]
pub struct Ast<'a> { /* fields omitted */ }
Expand description
An abstract syntax tree, contains all the nodes used in the code
Implementations
Will update the positions of all the tokens in the tree Necessary if you are both mutating the tree and need the positions of the tokens
Create an Ast from the passed tokens. You probably want parse
Errors
If the tokens passed are impossible to get through normal tokenization, an error of Empty (if the vector is empty) or NoEof (if there is no eof token) will be returned.
More likely, if the tokens pass are invalid Lua 5.1 code, an UnexpectedToken error will be returned.
Returns a new Ast with the given nodes
Returns a new Ast with the given EOF token
The entire code of the function
assert_eq!(full_moon::parse("local x = 1; local y = 2")?.nodes().stmts().count(), 2);
The EOF token at the end of every Ast
Trait Implementations
The start position of a node. None if can’t be determined
The end position of a node. None if it can’t be determined
Whether another node of the same type is the same as this one semantically, ignoring position
The token references that comprise a node
The full range of a node, if it has both start and end positions
The tokens surrounding a node that are ignored and not accessible through the node’s own accessors. Use this if you want to get surrounding comments or whitespace. Returns a tuple of the leading and trailing trivia. Read more
