Implementations

impl DockerfileTokenType

pub fn is_instruction(&self) -> bool

Returns true if this token type is a Dockerfile instruction.

pub fn is_trivia(&self) -> bool

Returns true if this token type is a trivia token (whitespace, newline, or comment).

Trait Implementations

impl Clone for DockerfileTokenType

fn clone(&self) -> DockerfileTokenType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DockerfileTokenType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DockerfileTokenType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<DockerfileTokenType> for DockerfileElementType

fn from(token: DockerfileTokenType) -> Self

Converts to this type from the input type.

impl Hash for DockerfileTokenType

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 DockerfileTokenType

fn eq(&self, other: &DockerfileTokenType) -> 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 DockerfileTokenType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TokenType for DockerfileTokenType

const END_OF_STREAM: Self = Self::Eof

A constant representing the end of the input stream.

type Role = UniversalTokenRole

The associated role type for this token kind.

fn is_ignored(&self) -> bool

Returns true if this token represents trivia (whitespace, comments, etc.).

fn role(&self) -> Self::Role

Returns the general syntactic role of this token.

fn is_role(&self, role: Self::Role) -> bool

Returns true if this token matches the specified language-specific role.

fn is_universal(&self, role: UniversalTokenRole) -> bool

Returns true if this token matches the specified universal role.

fn is_comment(&self) -> bool

Returns true if this token represents a comment.

fn is_whitespace(&self) -> bool

Returns true if this token represents whitespace.

fn is_error(&self) -> bool

Returns true if this token represents an error condition.

fn is_end_of_stream(&self) -> bool

Returns true if this token represents the end of the input stream.
