Struct DebugInfo

#[non_exhaustive]
pub struct DebugInfo {
    pub instructions: HashMap<usize, DebugInst>,
    pub functions: HashMap<Hash, DebugSignature>,
    pub functions_rev: HashMap<usize, Hash>,
    pub hash_to_ident: HashMap<Hash, Box<str>>,
}

Debug information about a unit.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

instructions: HashMap<usize, DebugInst>

Debug information on each instruction.

functions: HashMap<Hash, DebugSignature>

Function signatures.

functions_rev: HashMap<usize, Hash>

Reverse lookup of a function.

hash_to_ident: HashMap<Hash, Box<str>>

Hash to identifier.

Implementations

impl DebugInfo

pub fn instruction_at(&self, ip: usize) -> Option<&DebugInst>

Get debug instruction at the given instruction pointer.

pub fn function_at(&self, ip: usize) -> Option<(Hash, &DebugSignature)>

Get the function corresponding to the given instruction pointer.

pub fn ident_for_hash(&self, hash: Hash) -> Option<&str>

Access an identifier for the given hash - if it exists.

Trait Implementations

impl Debug for DebugInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DebugInfo

fn default() -> DebugInfo

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DebugInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for DebugInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryClone for DebugInfo

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.
