export const loadSvgResources = (ir: MatIconRegistry, ds: DomSanitizer) => {

const imgDir = 'assets/img';

const sidebarDir = `${imgDir}/sidebar`;

const dayDir = `${imgDir}/days`;

ir.addSvgIcon('day', ds.bypassSecurityTrustResourceUrl(`${sidebarDir}/day.svg`));

ir.addSvgIcon('month', ds.bypassSecurityTrustResourceUrl(`${sidebarDir}/month.svg`));

ir.addSvgIcon('project', ds.bypassSecurityTrustResourceUrl(`${sidebarDir}/project.svg`));

ir.addSvgIcon('projects', ds.bypassSecurityTrustResourceUrl(`${sidebarDir}/projects.svg`));

ir.addSvgIcon('week', ds.bypassSecurityTrustResourceUrl(`${sidebarDir}/week.svg`));

}

export const loadSvgResources = (ir: MatIconRegistry, ds: DomSanitizer) => {...}这是定义一个方法吗？

ir: MatIconRegistry, ds: DomSanitizer这个参数是代表将MatIconRegistry赋值给ir的意思吗？
