Struct ArgInstruction

pub struct ArgInstruction {
    pub span: Span,
    pub name: SpannedString,
    pub value: Option<SpannedString>,
}

A Dockerfile ARG instruction.

Fields

span: Span

name: SpannedString

The argument key

value: Option<SpannedString>

An optional argument value.

This may be unset when passing arguments through to later stages in a multi-stage build.

Trait Implementations

impl Clone for ArgInstruction

fn clone(&self) -> ArgInstruction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgInstruction

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

Formats the value using the given formatter.

impl From<ArgInstruction> for Instruction

fn from(ins: ArgInstruction) -> Self

Converts to this type from the input type.

impl PartialEq for ArgInstruction

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a> TryFrom<&'a Instruction> for &'a ArgInstruction

type Error = Error

The type returned in the event of a conversion error.

fn try_from(instruction: &'a Instruction) -> Result<Self, Self::Error>

Performs the conversion.
