Detailed Description

◆ op

enum class scilex::mode_action::op

strong

◆ operation

op scilex::mode_action::operation

Which transition to perform.

Definition at line 73 of file lexer.hpp.

◆ target

std::string scilex::mode_action::target {}

The mode push/set enters; ignored (and omittable) for pop.

Definition at line 74 of file lexer.hpp.

◆ target_id

std::size_t scilex::mode_action::target_id {0}

The interned id of target, resolved once when the lexer is built (see scilex::lexer::build_dispatch) so the per-token transition is a field read, not a name→id map lookup. Internal cache: a caller leaves it at 0 and sets only target; pop leaves it unused.
