Struct 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 code point offsets where newlines \n 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 code point offset within the 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 duplicate of the value.

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.

impl Default for SourceInfo

fn default() -> Self

Returns the “default value” for a type.

impl Message for SourceInfo

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for SourceInfo

const NAME: &'static str = "SourceInfo"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "google.api.expr.v1alpha1"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for SourceInfo

fn eq(&self, other: &SourceInfo) -> 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 StructuralPartialEq for SourceInfo
