Struct Lattice 

pub struct Lattice<'a> { /* private fields */ }

A MeCab lattice representing a search space for morphological analysis. It wraps C mecab_lattice_t.

The lifetime parameter is bound to Model.

Implementations

impl<'a> Lattice<'a>

pub fn as_ptr(&self) -> *mut mecab_lattice_t

Returns the raw pointer to the underlying mecab_lattice_t.

The pointer is guaranteed to be NonNull.

pub fn new(model: &'a Model) -> Result<Self, Error>

Creates a new Lattice from a Model.

It wraps mecab_model_new_lattice(), the wrapper of MeCab::Model::createLattice().

pub fn set_sentence<'l, 's>( &'l mut self, s: &'s str, ) -> LatticeGuard<'a, 'l, 's>

Sets the sentence to be analyzed and returns a LatticeGuard.

It wraps mecab_lattice_set_sentence2(), the wrapper of MeCab::Lattice::set_sentence(sentence, len).

Since the analysis result is borrowed from the input s, the input should be captured in a LatticeGuard during analysis.

pub fn clear(&mut self)

Clears the lattice.

It wraps mecab_lattice_clear(), the wrapper of MeCab::Lattice::clear().

pub fn is_available(&self) -> bool

Returns true if the lattice is available.

It wraps mecab_lattice_is_available(), the wrapper of MeCab::Lattice::is_available().

pub fn crf_norm_factor(&self) -> f64

Returns the CRF normalization factor.

It wraps mecab_lattice_get_z(), the wrapper of MeCab::Lattice::Z().

pub fn set_crf_norm_factor(&mut self, z: f64)

Sets the CRF normalization factor.

It wraps mecab_lattice_set_z(), the wrapper of MeCab::Lattice::set_Z().

pub fn temparature(&self) -> f64

Returns the temperature parameter.

It wraps mecab_lattice_get_theta(), the wrapper of MeCab::Lattice::theta().

pub fn set_temparature(&mut self, theta: f64)

Sets the temperature parameter.

It wraps mecab_lattice_set_theta(), the wrapper of MeCab::Lattice::set_theta().

pub fn request_type(&self) -> RequestType

Returns the request type flags.

It wraps mecab_lattice_get_request_type(), the wrapper of MeCab::Lattice::request_type().

pub fn set_request_type(&mut self, request_type: RequestType)

Sets the request type flags.

It wraps mecab_lattice_set_request_type(), the wrapper of MeCab::Lattice::set_request_type().

pub fn boundary_constraint(&self, pos: usize) -> BoundaryConstraintType

Returns the boundary constraint at the given position.

It wraps mecab_lattice_get_boundary_constraint(), the wrapper of MeCab::Lattice::boundary_constraint(pos).

pub fn set_boundary_constraint( &mut self, pos: usize, constraint: BoundaryConstraintType, )

Sets the boundary constraint at the given position.

It wraps mecab_lattice_set_boundary_constraint(), the wrapper of MeCab::Lattice::boundary_constraint(pos, type).

Trait Implementations

impl<'a> AsMut<Lattice<'a>> for LatticeGuard<'a, '_, '_>

fn as_mut(&mut self) -> &mut Lattice<'a>

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

impl<'a> AsRef<Lattice<'a>> for LatticeGuard<'a, '_, '_>

fn as_ref(&self) -> &Lattice<'a>

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

impl Drop for Lattice<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
