Trait Implementations

impl AsRef<str> for WriterFeatures

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for WriterFeatures

fn clone(&self) -> WriterFeatures

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WriterFeatures

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WriterFeatures

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for WriterFeatures

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

Formats the value using the given formatter.

impl From<&Field> for WriterFeatures

fn from(value: &Field) -> Self

Converts to this type from the input type.

impl From<&str> for WriterFeatures

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for WriterFeatures

fn from(value: String) -> Self

Converts to this type from the input type.

impl Hash for WriterFeatures

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WriterFeatures

fn eq(&self, other: &WriterFeatures) -> 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 Serialize for WriterFeatures

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&TableFeatures> for WriterFeatures

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: &TableFeatures) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for WriterFeatures

impl StructuralPartialEq for WriterFeatures
