Struct wasmtime_environ::FilePos

pub struct FilePos(_);

A position within an original source file,

This structure is used as a newtype wrapper around a 32-bit integer which represents an offset within a file where a wasm instruction or function is to be originally found.

Implementations

impl FilePos

pub fn new(pos: u32) -> FilePos

Create a new file position with the given offset.

pub fn file_offset(self) -> Option<u32>

Returns the offset that this offset was created with.

Note that the Default implementation will return None here, whereas positions created with FilePos::new will return Some.

Trait Implementations

impl Clone for FilePos

fn clone(&self) -> FilePos

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FilePos

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

Formats the value using the given formatter.

impl Default for FilePos

fn default() -> FilePos

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FilePos

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<FilePos> for FilePos

fn eq(&self, other: &FilePos) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FilePos

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

Serialize this value into the given Serde serializer.
