Implementations

source

impl Term

source

pub fn is_empty(&self) -> bool

Is empty if there are no value bytes.

source

pub fn from_field_ip_addr(field: Field, ip_addr: Ipv6Addr) -> Term

Builds a term given a field, and a Ipv6Addr-value

source

pub fn from_field_u64(field: Field, val: u64) -> Term

Builds a term given a field, and a u64-value

source

pub fn from_field_i64(field: Field, val: i64) -> Term

Builds a term given a field, and a i64-value

source

pub fn from_field_f64(field: Field, val: f64) -> Term

Builds a term given a field, and a f64-value

source

pub fn from_field_bool(field: Field, val: bool) -> Term

Builds a term given a field, and a bool-value

source

pub fn from_field_date(field: Field, val: DateTime) -> Term

Builds a term given a field, and a DateTime value

source

pub fn from_facet(field: Field, facet: &Facet) -> Term

source

pub fn from_field_text(field: Field, text: &str) -> Term

Builds a term given a field, and a string value

source

pub fn from_field_bytes(field: Field, bytes: &[u8]) -> Term

Builds a term bytes.

source

pub fn clear_with_type(&mut self, typ: Type)

source

pub fn set_u64(&mut self, val: u64)

Sets a u64 value in the term.

U64 are serialized using (8-byte) BigEndian representation. The use of BigEndian has the benefit of preserving the natural order of the values.

Sets a i64 value in the term.

source

pub fn set_date(&mut self, date: DateTime)

Sets a DateTime value in the term.

Sets a f64 value in the term.

source

pub fn set_bool(&mut self, val: bool)

Sets a bool value in the term.

source

pub fn set_ip_addr(&mut self, val: Ipv6Addr)

source

pub fn set_text(&mut self, text: &str)

Set the texts only, keeping the field untouched.

source

pub fn truncate_value_bytes(&mut self, len: usize)

Truncates the value bytes of the term. Value and field type stays the same.

Returns None if the term is not of the bool type, or if the term byte representation is invalid.

source

pub fn as_date(&self) -> Option<DateTime>

Returns the Date value stored in a term.

Returns None if the term is not of the Date type, or if the term byte representation is invalid.

source

pub fn as_str(&self) -> Option<&str>

Returns the text associated with the term.

Returns None if the field is not of string type or if the bytes are not valid utf-8.

source

pub fn as_facet(&self) -> Option<Facet>

Returns the facet associated with the term.

Returns None if the field is not of facet type or if the bytes are not valid utf-8.

source

pub fn as_bytes(&self) -> Option<&[u8]>

Returns the bytes associated with the term.

Returns None if the field is not of bytes type.

source

pub fn value_bytes(&self) -> &[u8]

Returns the serialized value of the term. (this does not include the field.)

If the term is a string, its value is utf-8 encoded. If the term is a u64, its value is encoded according to byteorder::LittleEndian.
