Struct Rule

pub struct Rule(/* private fields */);

An AST node for $ast

Implementations

impl Rule

pub fn targets(&self) -> impl Iterator<Item = String>

Targets of this rule

Example

use makefile_lossless::Rule;

let rule: Rule = "rule: dependency\n\tcommand".parse().unwrap();
assert_eq!(rule.targets().collect::<Vec<_>>(), vec!["rule"]);

pub fn prerequisites(&self) -> impl Iterator<Item = String>

Get the prerequisites in the rule

Example

use makefile_lossless::Rule;
let rule: Rule = "rule: dependency\n\tcommand".parse().unwrap();
assert_eq!(rule.prerequisites().collect::<Vec<_>>(), vec!["dependency"]);

pub fn recipes(&self) -> impl Iterator<Item = String>

Get the commands in the rule

Example

use makefile_lossless::Rule;
let rule: Rule = "rule: dependency\n\tcommand".parse().unwrap();
assert_eq!(rule.recipes().collect::<Vec<_>>(), vec!["command"]);

pub fn replace_command(&self, i: usize, line: &str)

Replace the command at index i with a new line

Example

use makefile_lossless::Rule;
let rule: Rule = "rule: dependency\n\tcommand".parse().unwrap();
rule.replace_command(0, "new command");
assert_eq!(rule.recipes().collect::<Vec<_>>(), vec!["new command"]);
assert_eq!(rule.to_string(), "rule: dependency\n\tnew command\n");

pub fn push_command(&self, line: &str)

Add a new command to the rule

Example

use makefile_lossless::Rule;
let rule: Rule = "rule: dependency\n\tcommand".parse().unwrap();
rule.push_command("command2");
assert_eq!(rule.recipes().collect::<Vec<_>>(), vec!["command", "command2"]);

Trait Implementations

impl AstNode for Rule

type Language = Lang

fn can_cast(kind: SyntaxKind) -> bool

fn cast(syntax: SyntaxNode<Lang>) -> Option<Self>

fn syntax(&self) -> &SyntaxNode<Lang>

fn clone_for_update(&self) -> Self

where Self: Sized,

fn clone_subtree(&self) -> Self

where Self: Sized,

impl Display for Rule

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromStr for Rule

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Rule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Rule

fn eq(&self, other: &Rule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
