Source diagnostics

Detailed Description

Classify compilation failures and locate them with half-open UTF-8 byte intervals. Client-emitter and execution exceptions propagate independently.

Classes
struct	cel::source_span
	Identifies a half-open UTF-8 byte interval; begin never exceeds end. Example: source_span{0, 4} covers all bytes of "true". More...
class	cel::parse_error
	Owns a source-located diagnostic; copied diagnostics own independent messages. Example: parse_error(error_category::malformed_input, {0, 1}, "invalid input"). More...

Enumerations
enum class	cel::error_category {   cel::error_category::malformed_input , cel::error_category::unsupported_literal , cel::error_category::type_error , cel::error_category::lookup_error ,   cel::error_category::delimiter_error , cel::error_category::resource_limit }
	Classifies a source diagnostic independently of its human-readable message. Example: error_category::unsupported_literal identifies an f32 suffix. More...

enum class cel::error_category

strong

Classifies a source diagnostic independently of its human-readable message. Example: error_category::unsupported_literal identifies an f32 suffix.

Enumerator
malformed_input	Invalid UTF-8, spelling, comment, or input character.
unsupported_literal	A literal or suffix outside bool/binary64 scope.
type_error	An unknown, unsupported, ineligible, or incompatible type.
lookup_error	An undefined name or unmatched operation signature.
delimiter_error	An unmatched, mismatched, or unclosed delimiter.
resource_limit	A documented producer or compilation resource limit.
