Struct EntrypointInstruction

pub struct EntrypointInstruction {
    pub span: Span,
    pub expr: ShellOrExecExpr,
}

A Dockerfile ENTRYPOINT instruction.

An entrypoint may be defined as either a single string (to be run in the default shell), or a list of strings (to be run directly).

Fields

span: Span

expr: ShellOrExecExpr

Implementations

impl EntrypointInstruction

pub fn into_shell(self) -> Option<BreakableString>

Unpacks this instruction into its inner value if it is a Shell-form instruction, otherwise returns None.

pub fn as_shell(&self) -> Option<&BreakableString>

Unpacks this instruction into its inner value if it is a Shell-form instruction, otherwise returns None.

pub fn into_exec(self) -> Option<StringArray>

Unpacks this instruction into its inner value if it is an Exec-form instruction, otherwise returns None.

pub fn as_exec(&self) -> Option<&StringArray>

Unpacks this instruction into its inner value if it is an Exec-form instruction, otherwise returns None.

Trait Implementations

impl Clone for EntrypointInstruction

fn clone(&self) -> EntrypointInstruction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntrypointInstruction

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

Formats the value using the given formatter.

impl From<EntrypointInstruction> for Instruction

fn from(ins: EntrypointInstruction) -> Self

Converts to this type from the input type.

impl PartialEq for EntrypointInstruction

fn eq(&self, other: &EntrypointInstruction) -> 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 TryFrom<Instruction> for EntrypointInstruction

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
