Enum Code 

pub enum Code {
    Data(Problem),
    Tool(Atom),
}

A diagnostic’s kind: one of this crate’s Problems, or a tool’s own code (E0308, a lint’s name), kept as an Atom. Written as its code in every form.

Variants

Data(Problem)

One of this crate’s problems (SD0001).

Tool(Atom)

A tool’s own code (E0308).

Implementations

impl Code

pub fn tool(code: Atom) -> Code

A tool’s own code; one of this crate’s codes is that Problem.

pub fn as_str(self) -> &'static str

As written: SD0001, E0308.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Code

impl Debug for Code

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

Formats the value using the given formatter.

impl Display for Code

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

Formats the value using the given formatter.

impl Eq for Code

impl From<Atom> for Code

fn from(a: Atom) -> Code

Converts to this type from the input type.

impl From<Problem> for Code

fn from(p: Problem) -> Code

Converts to this type from the input type.

impl Hash for Code

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Code

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

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<Problem> for Code

fn eq(&self, p: &Problem) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Schema for Code

Written as its code; packed in a frame as an Atom (its number).

fn shape() -> Shape

What the format looks like.

fn read(v: &ValueRef<'_>, cx: &mut Reader<'_>) -> Option<Self>

Reads v. Problems go to cx at its current path; None when the value couldn’t be read (the problem is in cx).

fn write(&self) -> Value

The value, as the format writes it.

fn encode(&self, w: &mut Writer)

Writes itself in the binary form, straight — Schema::write’s value encoded, unless the type knows better (derived ones do).

fn decode(d: &mut Decoder<'_>) -> Option<Self>

Reads itself from the binary form, straight; None when it isn’t what Schema::encode writes — then read_bytes reads the slow way, which says what’s wrong. Through a value unless the type knows better (derived ones do).

fn pack(&self, p: &mut Packer)

Packs itself into a frame (crate::frame): its binary form as bytes, unless the type packs itself (derived ones and plain types do).

fn unpack(u: &mut Unpacker<'_>) -> Option<Self>

Reads itself out of a frame; None if the bytes aren’t what Schema::pack writes.

fn absent() -> Option<Self>

The value of a field that isn’t there — None: the field is required.

fn skip(&self) -> bool

Whether a struct leaves this field out when writing it.

fn write_text(&self, w: &mut Writer)

Writes itself as text, straight (crate::text::Writer) — Schema::write’s value as text, unless the type knows better (derived ones do): no value tree is built on the way.

fn pack_list(items: &[Self], p: &mut Packer)

A list of these packed: a count, then each one (floats raw).

fn unpack_list(u: &mut Unpacker<'_>) -> Option<Vec<Self>>

A list of these out of a frame.

fn encode_list(items: &[Self], w: &mut Writer)

A list of these written straight (numbers pack theirs).

fn decode_list(d: &mut Decoder<'_>) -> Option<Vec<Self>>

A list of these read straight.
