Struct CrateData 

pub struct CrateData<R> { /* private fields */ }

High level interface to binary data.

Implementations

impl<R> CrateData<R>

where R: Read + Seek,

pub fn open(reader: R, safe: bool) -> Result<Self>

Read binary data from any reader.

Trait Implementations

impl<R> AbstractData for CrateData<R>

where R: Read + Seek,

fn has_spec(&self, path: &Path) -> bool

Returns true if this data has a spec for the given path.

fn has_field(&self, path: &Path, field: &str) -> bool

Returns true if this data has a field for the given path.

fn spec_type(&self, path: &Path) -> Option<SpecType>

Returns the type of the spec at the given path.

fn try_field( &self, path: &Path, field: &str, ) -> Result<Option<Cow<'_, Value>>, DataError>

Returns the value for a field, or None if not authored.

fn list_fields(&self, path: &Path) -> Option<Vec<String>>

Returns the field names for a given path in authored order.

fn spec_paths(&self) -> Vec<Path>

Returns every authored path, sorted lexicographically.

fn create_spec(&mut self, path: Path, ty: SpecType)

Creates an empty spec of type ty at path, replacing any existing spec there. Mirrors C++ SdfAbstractData::CreateSpec. Fields are authored separately via set_field.

fn erase_spec(&mut self, path: &Path)

Removes the spec at path along with all its fields. Mirrors C++ SdfAbstractData::EraseSpec. No-op if no spec exists there.

fn set_field(&mut self, path: &Path, field: &str, value: Value)

Sets (or replaces) field on the spec at path, preserving authored field order. Mirrors C++ SdfAbstractData::Set. The spec must already exist (create it with create_spec first); setting a field on an absent spec drops the write (debug builds assert).

fn erase_field(&mut self, path: &Path, field: &str)

Removes field from the spec at path. Mirrors C++ SdfAbstractData::EraseField. No-op if the spec or field is absent.

fn get_field( &self, path: &Path, field: &str, ) -> Result<Cow<'_, Value>, DataError>

Returns the value for a field, erroring if not authored.
