Struct gapi_grpc::google::api::expr::v1alpha1::SourceInfo

pub struct SourceInfo {
    pub syntax_version: String,
    pub location: String,
    pub line_offsets: Vec<i32>,
    pub positions: HashMap<i64, i32>,
    pub macro_calls: HashMap<i64, Expr>,
}

Source information collected at parse time.

Fields

syntax_version: String

The syntax version of the source, e.g. cel1.

location: String

The location name. All position information attached to an expression is relative to this location.

The location could be a file, UI element, or similar. For example, acme/app/AnvilPolicy.cel.

line_offsets: Vec<i32>

Monotonically increasing list of character offsets where newlines appear.

The line number of a given position is the index i where for a given id the line_offsets[i] < id_positions[id] < line_offsets[i+1]. The column may be derivd from id_positions[id] - line_offsets[i].

positions: HashMap<i64, i32>

A map from the parse node id (e.g. Expr.id) to the character offset within source.

macro_calls: HashMap<i64, Expr>

A map from the parse node id where a macro replacement was made to the call Expr that resulted in a macro expansion.

For example, has(value.field) is a function call that is replaced by a test_only field selection in the AST. Likewise, the call list.exists(e, e > 10) translates to a comprehension expression. The key in the map corresponds to the expression id of the expanded macro, and the value is the call Expr that was replaced.

Trait Implementations

impl Clone for SourceInfo

fn clone(&self) -> SourceInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceInfo

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

Formats the value using the given formatter.
