Struct FormatCosts 

pub struct FormatCosts {
    pub format_costs: Option<Vec<FormatCostEntry>>,
}

This is the root of the persistent fidl in a format costs file. The format costs files are read by the assembly tool and merged into the single sysmem_config.persistent_fidl file in the sysmem domain config (see Config above).

Normally json[5] would be preferable for config, but we generate this config in rust using FIDL types (to avoid repetition and to take advantage of FIDL rust codegen), and there’s no json schema for FIDL types.

While the resulting sysmem_config.persistent_fidl is a single file that can contain multiple aspects of sysmem config, in contrast a format costs file contains only format costs. We don’t mind having more separate files during the build, but it’s nice to get sysmem’s domain config down to a single file on-device.

Trait Implementations

impl Clone for FormatCosts

fn clone(&self) -> FormatCosts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatCosts

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

Formats the value using the given formatter.

impl Default for FormatCosts

fn default() -> FormatCosts

Returns the “default value” for a type.

impl<'a, ___E> Encode<FormatCosts<'static>, ___E> for &'a FormatCosts

where ___E: Encoder + ?Sized,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<FormatCosts<'static>>, _: (), ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl<___E> Encode<FormatCosts<'static>, ___E> for FormatCosts

where ___E: Encoder + ?Sized,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<FormatCosts<'static>>, _: (), ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl<'de> FromWire<FormatCosts<'de>> for FormatCosts

fn from_wire(wire_: FormatCosts<'de>) -> FormatCosts

Converts the given owned value to this type.

const COPY_OPTIMIZATION: CopyOptimization<W, Self> = _

Whether the conversion from W to Self is equivalent to copying the raw bytes of W.

impl<'de> FromWireRef<FormatCosts<'de>> for FormatCosts

fn from_wire_ref(wire: &FormatCosts<'de>) -> FormatCosts

Converts the given reference to this type.

impl PartialEq for FormatCosts

fn eq(&self, other: &FormatCosts) -> 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 PartialOrd for FormatCosts

fn partial_cmp(&self, other: &FormatCosts) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
