Struct ServiceError 

pub struct ServiceError {
    pub message: String,
    pub problems: Vec<Problem>,
    pub file: Option<String>,
}

The error a request is answered with.

Fields

message: String

problems: Vec<Problem>

Every problem, each with its code; at least one.

file: Option<String>

The file the request is about, when it’s about one.

Implementations

impl ServiceError

pub fn of(code: &str, message: impl Into<String>) -> Self

One problem of kind code.

pub fn at( code: &str, message: impl Into<String>, line: u32, col: Option<u32>, ) -> Self

message of kind code, about the text at line:col.

pub fn syntax(e: &SyntaxError) -> Self

Text that doesn’t parse.

pub fn not_found(message: impl Into<String>) -> Self

What a request names isn’t there.

pub fn param(name: &str, problems: Vec<Problem>) -> Self

Parameter name that doesn’t read: each of its problems, at its path.

Trait Implementations

impl Clone for ServiceError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceError

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

Formats the value using the given formatter.

impl Default for ServiceError

fn default() -> Self

Returns the “default value” for a type.

impl Fields for ServiceError

const FIELDS: &'static [(&'static str, &'static str)]

impl From<&str> for ServiceError

fn from(message: &str) -> Self

Converts to this type from the input type.

impl From<String> for ServiceError

fn from(message: String) -> Self

Converts to this type from the input type.

impl PartialEq for ServiceError

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

Equality operator ==.

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

Inequality operator !=.

impl Schema for ServiceError

fn encode(&self, __yog_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(__yog_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, __yog_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(__yog_u: &mut Unpacker<'_>) -> Option<Self>

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

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 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 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.
