Implementations

impl Fragment

pub fn text(&self) -> &str

Get the text value of the fragment

pub fn line(&self) -> StatementLine

Get line position

pub fn column(&self) -> StatementColumn

Get column position

pub fn sub_fragment(&self, offset: usize, length: usize) -> Fragment

Get a sub-fragment starting at the given offset with the given length

pub fn with_text(&self, text: impl AsRef<str>) -> Fragment

Return a new fragment with replaced text, preserving location info.

impl Fragment

pub fn internal(text: impl AsRef<str>) -> Self

Create an internal fragment - useful for creating fragments from substrings.

Takes impl AsRef<str> so Arc::<str>::from(&str) allocates the inline Arc payload directly, skipping the implicit String round trip that the previous impl Into<String> signature forced.

pub fn testing(text: impl AsRef<str>) -> Self

Create a testing fragment - returns a Statement fragment for test purposes.

Takes impl AsRef<str> so Arc::<str>::from(&str) allocates the inline Arc payload directly, skipping the implicit String round trip that the previous impl Into<String> signature forced.

pub fn testing_empty() -> Self

Create an empty testing fragment

pub fn merge_all(fragments: impl IntoIterator<Item = Fragment>) -> Fragment

Merge multiple fragments (in any order) into one encompassing fragment

pub fn fragment(&self) -> &str

Compatibility: expose fragment field for Fragment compatibility

impl Fragment

pub fn statement(text: impl AsRef<str>, line: u32, column: u32) -> Self

Create a statement fragment with position info

pub fn none() -> Self

Create a none fragment
