Struct c2rust_transpile::cfg::DeclStmtStore

pub struct DeclStmtStore { /* fields omitted */ }

Stores information about translating C declarations to Rust statements. When seeing a C declaration, we often don't know if it is already in the right place. The fix is to punt: we put into a DeclStmtStore information about what to do in all possible cases and we delay choosing what to do until later.

Methods

impl DeclStmtStore

pub fn new() -> Self

pub fn absorb(&mut self, other: DeclStmtStore)

pub fn extract_decl(
    &mut self,
    decl_id: CDeclId
) -> Result<Vec<Stmt>, TranslationError>

Extract just the Rust statements for a declaration (without initialization). Used when you want to move just a declaration to a larger scope.

pub fn extract_assign(
    &mut self,
    decl_id: CDeclId
) -> Result<Vec<Stmt>, TranslationError>

Extract just the Rust statements for an initializer (without the declaration it was initially attached to). Used when you've moved a declaration but now you need to also run the initializer.

pub fn extract_decl_and_assign(
    &mut self,
    decl_id: CDeclId
) -> Result<Vec<Stmt>, TranslationError>

Extract the Rust statements for the full declaration and initializers. Used for when you didn't need to move a declaration at all.

pub fn peek_decl_and_assign(
    &self,
    decl_id: CDeclId
) -> Result<Vec<Stmt>, TranslationError>

Extract the Rust statements for the full declaration and initializers. DEBUGGING ONLY.
