⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Registers a read in the dependency graph of the AST node with the given id. This needs to be called each time a public function returns the HIR for a node -- in other words, when it "reveals" the content of a node to the caller (who might not otherwise have had access to those contents, and hence needs a read recorded). If the function just returns a DefId or HirId, no actual content was returned, so no read is needed.

pub fn get_parent_node(&self, hir_id: HirId) -> HirId[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Similar to get_parent; returns the parent HIR Id, or just hir_id if there is no parent. Note that the parent may be CRATE_HIR_ID, which is not itself present in the map, so passing the return value of get_parent_node to get may in fact panic. This function returns the immediate parent in the HIR, whereas get_parent returns the enclosing item. Note that this might not be the actual parent node in the HIR -- some kinds of nodes are not in the map and these will never appear as the parent node. Thus, you can always walk the parent nodes from a node to the root of the HIR (unless you get back the same ID here, which can happen if the ID is not in the map itself or is just weird).

pub fn is_argument(&self, id: HirId) -> bool[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

If there is some error when walking the parents (e.g., a node does not have a parent in the map or a node can't be found), then we return the last good HirId we found. Note that reaching the crate root (id == 0), is not an error, since items in the crate module have the crate root as parent.

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

fn foo(x: usize) -> bool {
    if x == 1 {
        true  // `get_return_block` gets passed the `id` corresponding
    } else {  // to this, it will return `foo`'s `HirId`.

    loop {
        true  // `get_return_block` gets passed the `id` corresponding
    }         // to this, it will return `None`.
    false
}
