Struct FormatOptions 

pub struct FormatOptions {
    pub verbose: Option<bool>,
    pub deprecated_padded_blobfs_format: Option<bool>,
    pub num_inodes: Option<u64>,
    pub fvm_data_slices: Option<u32>,
    pub sectors_per_cluster: Option<u16>,
    /* private fields */
}

Options for how to format filesystems.

Fields

verbose: Option<bool>

Enable verbose logging.

deprecated_padded_blobfs_format: Option<bool>

If true, use the deprecated padded merkle tree blobfs format.

num_inodes: Option<u64>

The initial number of inodes to allocate space for. If zero, a default is used. Only supported for blobfs.

fvm_data_slices: Option<u32>

The number of fvm slices to preallocate for data when the filesystem is created.

sectors_per_cluster: Option<u16>

The number of sectors-per-cluster (for FAT filesystems).

Trait Implementations

impl Clone for FormatOptions

fn clone(&self) -> FormatOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatOptions

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

Formats the value using the given formatter.

impl<D> Decode<FormatOptions, D> for FormatOptions

where D: ResourceDialect,

fn new_empty() -> FormatOptions

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<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

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

impl Default for FormatOptions

fn default() -> FormatOptions

Returns the “default value” for a type.

impl<D> Encode<FormatOptions, D> for &FormatOptions

where D: ResourceDialect,

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

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

impl PartialEq for FormatOptions

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

type Owned = FormatOptions

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 FormatOptions

type Borrowed<'a> = &'a FormatOptions

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( value: &<FormatOptions as TypeMarker>::Owned, ) -> <FormatOptions as ValueTypeMarker>::Borrowed<'_>

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