Struct Cst

pub struct Cst {
    pub uri: SmolStr,
    pub block: Block,
    pub errors: Vec<Error>,
    pub status: AstStatus,
}

A struct representing a scope in a file. This CST is lossless, meaning it can be printed back to the code it was created from without losing any details.

Fields

uri: SmolStr

The path pointing to the file that this CST represents.

block: Block

The block of code for this scope.

errors: Vec<Error>

All syntactical errors in this CST.

status: AstStatus

The status of the CST. If it isn’t complete, it’s better to not use it for operations which affect the source code, like formatting; the output will have missing parts of the code.

Implementations

impl Cst

pub fn has_errors(&self) -> bool

Whether or not this Cst has errors.

pub fn try_print(&self) -> Result<String, PrintingError>

Try printing the Cst back into source code.

Errors

This’ll only fail if Cst.has_errors() returns true.

Trait Implementations

impl Clone for Cst

fn clone(&self) -> Cst

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Cst

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

Formats the value using the given formatter.

impl Default for Cst

fn default() -> Cst

Returns the “default value” for a type.

impl Hash for Cst

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 Ord for Cst

fn cmp(&self, other: &Cst) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Cst

fn eq(&self, other: &Cst) -> 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.

impl PartialOrd for Cst

fn partial_cmp(&self, other: &Cst) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
