Struct fidl_fuchsia_component_decl::Program

pub struct Program {
    pub runner: Option<String>,
    pub info: Option<Dictionary>,
    /* private fields */
}

A program declaration.

This declaration is set by executable components to designate the runner to use and pass runner-specific program information to it.

To learn more about runners, see: https://fuchsia.dev/fuchsia-src/glossary#runner

Fields

runner: Option<String>

The name of the runner to use to run the component. Must match a RunnerRegistration in the component’s environment. If this value is not supplied, the component must ‘use’ a runner. If this value is supplied, the component may ‘use’ a runner, but it must be identical (matching name, from environment).

info: Option<Dictionary>

(Required) Information about the program to run when the component is executed. The component manager provides the contents of this dictionary to the runner when executing this program.

For instance, this might contain a path to the program’s executable image, or program arguments.

• The keys represent namespaced properties, delimited by “.”.
• Properties may be nested in values, but only in the case of an object vector.

Trait Implementations

impl Clone for Program

fn clone(&self) -> Program

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Program

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

Formats the value using the given formatter.

impl Decode<Program> for Program

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize, depth: Depth ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for Program

fn default() -> Program

Returns the “default value” for a type.

impl Encode<Program> for &Program

unsafe fn encode( self, encoder: &mut Encoder<'_>, offset: usize, depth: Depth ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Program

fn eq(&self, other: &Program) -> 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 TypeMarker for Program

type Owned = Program

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for Program

type Borrowed<'a> = &'a Program

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

Cheaply converts from &Self::Owned to Self::Borrowed.
