Struct VersionBuilder 

pub struct VersionBuilder { /* private fields */ }

Builder for creating Version programmatically.

This builder allows you to construct version strings when building DBC files programmatically by specifying a complete version string.

Examples

use dbc_rs::VersionBuilder;

// Direct version string
let version = VersionBuilder::new().version("1.0").build()?;
assert_eq!(version.as_str(), "1.0");

// Semantic versioning (as a string)
let version2 = VersionBuilder::new()
    .version("1.2.3")
    .build()?;
assert_eq!(version2.as_str(), "1.2.3");

Feature Requirements

This builder requires the std feature to be enabled.

Implementations

impl VersionBuilder

pub fn new() -> Self

Creates a new VersionBuilder with no version set.

Examples

use dbc_rs::VersionBuilder;

let builder = VersionBuilder::new();
// Must set version before building
let version = builder.version("1.0").build()?;

pub fn version(self, version: impl AsRef<str>) -> Self

Sets the complete version string.

Arguments

• version - The complete version string (e.g., “1.0”, “1.2.3”, “1.0-beta”)

Examples

use dbc_rs::VersionBuilder;

let version = VersionBuilder::new()
    .version("1.2.3")
    .build()?;
assert_eq!(version.as_str(), "1.2.3");

pub fn build(self) -> Result<Version>

Builds the Version from the builder configuration.

This validates that a version has been set and constructs a Version instance with static lifetime.

Returns

Returns Ok(Version) if successful, or Err(Error::Version) if:

• No version has been set (empty version)

Examples

use dbc_rs::VersionBuilder;

// Build with version string
let version = VersionBuilder::new()
    .version("1.0")
    .build()?;
assert_eq!(version.as_str(), "1.0");

Errors

use dbc_rs::VersionBuilder;

// Missing version
let result = VersionBuilder::new().build();
assert!(result.is_err());

// Empty string is allowed
let version = VersionBuilder::new().version("").build()?;
assert_eq!(version.as_str(), "");

Trait Implementations

impl Default for VersionBuilder

fn default() -> Self

Returns the “default value” for a type.
