pub const VT_ENDIANNESS: VOffsetT

pub const VT_FIELDS: VOffsetT

pub const VT_CUSTOM_METADATA: VOffsetT

pub const VT_FEATURES: VOffsetT

pub fn endianness(&self) -> Endianness

endianness of the buffer it is Little Endian by default if endianness doesn't match the underlying system then the vectors need to be converted

pub fn fields(&self) -> Option<Vector<'a, ForwardsUOffset<Field<'a>>>>

pub fn custom_metadata(
    &self
) -> Option<Vector<'a, ForwardsUOffset<KeyValue<'a>>>>

pub fn features(&self) -> Option<Vector<'a, Feature>>

Features used in the stream/file.

Trait Implementations

impl<'a> Clone for Schema<'a>

fn clone(&self) -> Schema<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Schema<'a>

impl<'a> Debug for Schema<'a>

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

Formats the value using the given formatter.

impl<'a> Follow<'a> for Schema<'a>

type Inner = Schema<'a>

fn follow(buf: &'a [u8], loc: usize) -> Self::Inner

impl<'a> PartialEq<Schema<'a>> for Schema<'a>

fn eq(&self, other: &Schema<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Schema<'a>) -> bool

This method tests for !=.
