Struct ion_rs::text::writer::TextWriter

pub struct TextWriter<W: Write> { /* fields omitted */ }

Implementations

impl<W: Write> TextWriter<W>

pub fn new(sink: W) -> TextWriter<W>

Constructs a new instance of TextWriter that writes values to the provided io::Write implementation.

pub fn output(&self) -> &W

Returns a reference to the underlying io::Write implementation.

pub fn flush(&mut self) -> IonResult<()>

Causes any buffered data to be written to the underlying io::Write implementation.

pub fn set_field_name(&mut self, name: &str)

Sets the current field name to name. If the TextWriter is currently positioned inside of a struct, the field name will be written before the next value. Otherwise, it will be ignored.

pub fn set_annotations(&mut self, annotations: &[&str])

Sets a list of annotations that will be applied to the next value that is written.

pub fn step_in(&mut self, ion_type: IonType) -> IonResult<()>

Begins a container (List, S-Expression, or Struct). If ion_type is not a container type, step_in will return an Err(IllegalOperation).

pub fn is_in_struct(&self) -> bool

Returns true if the TextWriter is currently positioned within a Struct.

pub fn step_out(&mut self) -> IonResult<()>

pub fn write_null(&mut self, ion_type: IonType) -> IonResult<()>

Writes an Ion null of the specified type.

pub fn write_bool(&mut self, value: bool) -> IonResult<()>

Writes the provided bool value as an Ion boolean.

pub fn write_i64(&mut self, value: i64) -> IonResult<()>

Writes the provided i64 value as an Ion integer.

pub fn write_f64(&mut self, value: f64) -> IonResult<()>

Writes the provided f64 value as an Ion float.

pub fn write_big_decimal(&mut self, value: &BigDecimal) -> IonResult<()>

Writes the provided BigDecimal value as an Ion decimal.

pub fn write_datetime(&mut self, value: &DateTime<FixedOffset>) -> IonResult<()>

Writes the provided DateTime value as an Ion timestamp.

pub fn write_symbol<S: AsRef<str>>(&mut self, value: S) -> IonResult<()>

Writes the provided &str value as an Ion symbol.

pub fn write_string<S: AsRef<str>>(&mut self, value: S) -> IonResult<()>

Writes the provided &str value as an Ion string.

pub fn write_blob(&mut self, value: &[u8]) -> IonResult<()>

Writes the provided byte array slice as an Ion blob.

pub fn write_clob(&mut self, _value: &[u8]) -> IonResult<()>

Writes the provided byte array slice as an Ion clob.
